Heat Up!

by PanicTheFirst - Jam Entry

Heat Up is about the ancient heat ray by Archimedes. He invented it to defend themselves from enemy ships with mirrors and sunlight.

Click on the mirrors and target the enemy ships. But beware of those with a shield. You will need to reflect the sunlight to get those.

Left Mouse Button - Control the mirrors
Escape - Menu

Software used:

This is a great concept. Archimedes was actually the first thing that popped into my head when the theme was announced. I could see a really cool tower defense game from this mechanic. Well done!

Mirror mechanics are great, low poly water is perfect.

I love the art, the reflection mechanics were very interesting, good job! I was able to get to about 7500 before realising it wasn't getting harder :P The shields were an interesting challenge, nicely done!

Very good idea! Found it a bit difficult though. I felt sometimes that whatever I do, some ships will pass through.

Am I the only one or is this pretty hard? By the way, great game idea. I love you graphics. Sounds matches well. Perhaps there could be a local multiplayer? ^^

Love the low poly art and the mechanic feels good to use.

I love it. It's not always easy. The sound effects are good but maybe a little bit of music would have been fine. Great work :)

A well made game with an interesting mechanic, the only problem is that it's a bit hard to utilize the mirroring feature. It would be nice if you could control the mirrors more easily.

Very good executed idea, simple and nice. :D

pretty neat revamp of the classic history, love the 3d lowpoly art and realization. It should go more up in difficulty (bigger ships or harder)

Good graphics and a cool idea. It became a lot more interesting when I realized you could control the big mirror on the other side!

First of all thanks for the feedback ^^
Nice game, I really like how you interpreted the theme, that's original!
Easy to control, the graphics are nice too, actually I was wondering what did you use for this low poly style?
Just two things I would point is the fact that we don't see very well the health of the ships (a bit covered by the sails), and also when the ships cross the finish line.
Good job for this entry! :)

great mechanic idea and take on the theme. the art assets were also a good fit. the controls were a bit awkward, i found it hard to quickly adjust the mirrors. id like a ghost ray showing where they would go if a ship wasn't in the way.

great work!

Thank you for the feedback, too. :)
For the models I use Blender. For the import settings in Unity I set normals to Calculate and Smoothing Angle to 0. That should give them the flat look. :)

Yay mirrors! I did something similar using mirrors too!

Very well made and love the graphics.

Oh, yeees! I love games with mirrors and reflections and yours one was quit good.

However the movements is a bit to harsh for me. At first, it was very hard to setup mirrors as I wanted (I got better results do not moving anything at all! x))

Also, it was frustrating that small mirrors work as lasers and the big mirror is just a mirror. Maybe, you need to add "the sun" or any other visible source of light to the scene to make the game more.. realistic, I said.

really awsome game mechanic, my only feedback would be to be able to change the position after you release the mouse button as opposed to having to click again, nice job!

Really unique concept! I included it in my compilation video series of Ludum Dare 36 games, if you’d like to take a look :)

Very interesting idea, and simple but fitting graphics, I managed to last for a while, but not sure how long is considered good :)

Hitting the single mirror on the other side is hard though if other ships are blocking you line to it.

I like the life bars on the ships but it's hard to see on low HP, maybe they should be more bright,or hover on top of the ship model.
A bit of music would have been nice to set some atmosphere.

nice entry, well done.

Nice idea! Got a high score of 8600. Low poly graphics were beautiful. I found I got survive for a really long time by just always having one mirror selected, and just putting my mouse cursor on the ship till it sank. To remedy this, I suggest playing with the positioning/quanitity of mirrors, and to perhaps have more "shielded" ships. Played it on stream, please watch the VOD if you like! Good job.

Gave this game a go, video here:

Fun little game, though a bigger map with more towers or more enemy types would do a lot to improve the fun, after a while it seems like just aiming the beam at ships, which can be less fun over time.

Great job! I really enjoyed this game, the only issue I had is that it would have helped to have some idea which mirror was currently selected. I really liked the pacing, which allowed for coming up with a strategy and adjusting as needed.

Mini Submission FAQ

TEAMS: Teams entering the Jam should pick a single representative to submit your game, or create a team specific account you can share. We currently do not support Team Voting, but sharing an account and together playing and rating games is acceptable.

CAN I ENTER BOTH EVENTS?: You should pick 1 event, whichever you think it’ll do better in. If the idea is strong, and everything plays well enough, you can go Compo. If you’re a perfectionist, and would prefer people to play a more polished game, do the Jam. Many solo participants enter the Jam.

If you made 2 games, unfortunately, the website doesn’t support multiple submissions per user. To submit your 2nd game, you will have to make a 2nd account. Only do this if you made 2 games. Alternatively, if one game is better than the other, then consider just entering the better game.

CAN I KEEP WORKING UNTIL THE DEADLINE?: Yes! Immediately after the 48 or 72 hours, we do something called Submission Hour. As the name suggests, it’s an extra hour for you to package, upload, and submit your games. If there were catastrophic issues trying submitting your game, or you misunderstood how submissions work, that’s okay. It happens. We’re flexible. If you need advice, check with the folks on IRC. If you need an admin, get in touch.

CAN I KEEP WORKING ON MY GAME?: Oh definitely! You should! But for the sake of judging, keep the Compo or Jam version around. You can include a link to the Post-Compo/Post-Jam version of your game on your games page, but sure your main links are the original version.

PORTS: Ports to other platforms can be done after the deadline. That said, the sooner you finish your port, the sooner people can play your game, improving your chances of placing in the final results. For best results, provide a Web version of your game, or a Windows version with no dependencies. Also be sure to rate at least 20 games to improve your visibility (Coolness).

MY GAME CRASHES, IS UNBEATABLE, OR I MADE A TYPO: We allow you to fix crashes, win condition, or tiny bugs after the deadline. In a sense, this is like “porting” to support more players. We leave this open to interpretation, but generally speaking your game should be identical to the game you submitted. No new features, just fixing mistakes you should have caught had you been better rested.

MY GAME DOESN’T SHOW UP: If you can’t find your game, it’s usually because the URL to your downloads are missing ‘http://‘. Fix your URLs ( and you will show up. Alternatively, if you just posted it, wait a minute. The cache may not have refreshed yet.

NOT LOGGED IN?: If you get a message about not being logged in, even though you are, it’s because your web browser cached the non-logged in page. You can fix this by either refreshing your cache or clearing your cache. CTRL+F5 in many browsers. Chrome is a bit more work. Press F12 to enable Developer Mode, then you can right click on the refresh button and select “Empty Cache and Hard Reload”. This option is unavailable if you are not in Developer Mode.
