Hello! To celebrate my 9th entry to Ludum Dare, I decided to really push myself on something a little more ambitious as far as Ludum Dare goes (Mainly I wanted to learn how to do interfaces properly). I'm pretty happy with the results!

Most of the game (Scripts, Art, Shaders, etc) was done from scratch - using things I learned how to make from another project similar to this called MezraMan ( - but I would like to thank 'invulse' for his Object Pooling script (I tried to write my own and everything went wrong) and the ProCore team for making it possible to make level editing in Unity like a million times easier. The MIDI used is of 'Slayer - Raining Blood' and is provided by Graham Downey (

Theovexus is a Doom-Clone where you play as a Robot (Named Theovexus, mainly because it sounds cool) whose main purpose had already been fulfilled, and spends the rest of its life collecting folk lore and epic tales through time and space. (Thats what the white block outside the main chamber was going to be) After partying with the leaders of a very old civilization - however - Theovexus had taken time to build a nice and quiet place for him to hold his stuff and to rest in until he felt better.

This was all well and good until a growing, much more advanced civilization of faux-cowboys wiped out the totally chill society so they could expand their colonies. Once they stumble upon the small cavern and start hauling everything off for research, Theo wakes up PISSED and vows the destruction of the rootin-tootin folks and everything they have.

I really like this idea a lot, and after the compo I'll probably be working to get a much, MUCH more polished thing done.

I hope you enjoy what I scrambled to learn and finish. Have an awesome day!

#LDJAM <----- Apparently this will summon the eldritch ones. Gotta ask them when Protomen Act III is coming out. :L

I really loved this - so polished for a 72 hour game jam. Like the 2D/3D shooter style is class. Well done.

A few things of note - the red full-screen flash was a bit much for me, a bit jittery. It was great to see clear feedback though. I could not kill any enemies, I think I'm just a shit shot - I ended up running frantically and that was still really fun.

I can't wait to see what you would do with this if developed further. I love how you had pick-ups and different weapons in already (way further than we got).

This was pretty fun! Couple of things I missed while playing: crosshairs and changing weapons with mouse wheel. Definitely looking forward for expanded version!

Did you do sprite billboarding with shaders? I had major problems to get billboards looking right in my entry, in the end I had to resort using Unity's particle system.

Yeah, sprite billboarding was done with shaders and the default sprite renderer. The main thing you gotta do to get it to work is to flip the vertcies (-v.vertex.x) and then you can have a _Scale to change the size (-(v.vertex.x)*_Scale). It should work okay after that. Here's the equation I used, which you can also find on Wikibooks under CG Programming:

o.vertex = mul(UNITY_MATRIX_P, mul(UNITY_MATRIX_MV, float4 (0,0,0,1)) - float4(-v.vertex.x*_Scale, -v.vertex.y*_Scale, 0, 0));

Hope this helps! Glad you had fun with my game, and I'll certainly implement those when I get the chance ^^

Really cool game. And it's better to aim with crosshair.

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.
