Ludum Dare 37 — December 9th-11th, 2016 — Theme: One Room

Well, Mike ran in to problems getting working properly with about 12 hours left in the Compo, so this is the backup plan.

White Room

by MementoGames - Jam Entry

The ball will keep bouncing off/on the walls and on every bounce, the ball color changes. You have to use your weapon to paint the color of the wall so it will match the color of the ball.

If the ball hits the wall of a different color, it’s game over.

Don't forget to check at the bottom left corner of the screen which color the ball is going to be next (see help!). Use it to plan ahead!

Standard FPS controls apply. Right mouse button looks at the ball.

Have fun!

Great idea! really original. The controls feel really tight and the game is pretty hard! Good job.

Very interesting idea. When the ball hit near the corner and change color, it will give player no time to react.

Great concept. Looks great, feels great. I would have really like to be able to scroll colors with my mouse wheel.

What a cool idea for a game! Would love to see this idea developed further. This would be a good way for people to practice FPS if they've never played one. Good work!

Great game, I also played with a bounce mecahnic in my (2D) game as well. I agree with Khaoz_Fang, there should be a delay to give the player time to react to the quick color change and bounce. the combination of both back and forth almost impossible at times.

I like the idea, but I have a few problems which i'm running into. First the ball keeps going right into an edge, meaning there is no time to react before it hits the second wall. Also, in tense situations its very hard to rememeber which key switches to which color.

The right mouse button to focus you on the ball is really interesting, I don't think I've seen that before. I find switching colours difficult with 1,2,3. I think right mouse button or the mouse wheel would be a better spot.

Really great concept, and I think if I could switch guns faster I'd love it.

Really slick game. Sometimes the ball goes in the corner and it's impossible to have enough time to change the color. This is a really complete package.

Very cool, I love the feel the music and sound fits well. The game mechanics themselves make this stand out..

Great and fun game! Super challenging!

The concept is original and fun to play but switching color with those buttons seems to abort some of the fun we can get ! Maybe look for a different method to change colors ! But still is good and 10/10 would play again soon :D

Thanks, everyone. We are loving the feedback!

About the wall corners, you have to use the colors indicator on the bottom right of the screen. The big one one is the current ball color and the small one is the next color the ball will be. You always have to think ahead... and practice a little bit. But yeah, we run out of time to improve the HUD. It could be so much better.

About the color changing keys, any idea on how to do it differently?

Thanks again!

Ops, the indicators are at the bottom left corner, not bottom right.

Dec 17, 2016 @ 1:08am

Great concept, looks super ambitious for a jam game. This is really interesting and challenging in a good way. Controls feels smooth, i really enjoyed it.

Awesome game good controls and tough to get good at it.

Dec 17, 2016 @ 7:08pm

Hey I liked your game it was actually fun.
And pls go and try out my game!

Dec 17, 2016 @ 7:10pm

I enjoyed this game a lot.

Dec 17, 2016 @ 7:12pm

Pretty nifty. Solid controls. Wish I could invert the mouse (am I the only one left who prefers that?). Otherwise, great concept and solid execution. :)

Dec 17, 2016 @ 8:19pm

Nice game and thanks for your feed back.
I had not that much time this year because I wrote 2 class tests the week afterwards.
If the time fits with my schedule I'm in next Ludum dare as well.

Solid controls and fun idea. Well executed. I don't think you need the delay that others are suggesting since you show the next two colors. It's just a matter of planning ahead.

I would suggest you center the color prompt in the screen so it's always in the players peripheral vision.

Dec 17, 2016 @ 8:38pm

Fun game. Really cool concept. Sometimes I had almost no time to react, but with some tuning it could be really awesome.

Dec 17, 2016 @ 11:30pm

Look really good but i can't change gun color on my macbook and i don't know what input change...

MementoGames says ...
Dec 17, 2016 @ 11:35pm

@fafastudio The keys are '1' '2' '3', but you press them and nothing happens?

Cool idea, and nice implementation. I got pretty frustrated about collisions with edges/corners where there's literally no opportunity to see what colors you're going to need, but I enjoyed this.

It was a creative idea. The art was really nice. It was a lot of fun. Good job. :D

Very interesting take on the theme. Good job!

Perfect! Interesting idea, FPS, good gameplay and smooth interface all in 72 hours. Awesome!

i really like it, a little feedback maybe Mouse Wheel for change color will make it more enjoyable .. although is a 10/10 for me ...

JayCee23 says ...
Dec 18, 2016 @ 8:07pm

Cool game. It seems a bit slow at times, though. Nothing really stops me from just painting every wall the ball's colour

Split82 says ...
Dec 18, 2016 @ 8:16pm

Nice idea and well implemented too. It would be maybe good to see the trajectory of the ball. Anyway very nice entry.

Dec 18, 2016 @ 9:13pm

Nice idea! It was nice to have time to think, I'm glad it was difficult but not ridiculously hard.

thedashdude says ...
Dec 18, 2016 @ 9:18pm

Shockingly fun. At first I thought the idea was kind of stupid but that was a blast. I liked the changing of the room after each wave. I think using 1-3 to choose colors was pretty clunky, I would recommend using the scroll wheel or maybe right click to cycle through colors.

Wow! This is a fantastic game! Well made and so nicely polished. I loved to so much. I see good potential in the game. It was so fun playing it. You should continue making it. Overall a fun game to play. Keep it up!

Really cool idea. I like the Bob Ross like comment at the end haha. I wish it easier to switch between colours. That really made it annoying for me.

Interesting idea! I have never played such a fun game in this LD!!!I love the game so much!

Tkachov says ...
Dec 21, 2016 @ 7:05am

Nice! Though I think gun's bullets should be faster (probably instantly changing wall's color), as sometimes with these bullets you just can't change the color in time. It's also a bit difficult when ball is bouncing really close to the edge, meaning there is almost no time for player to react.

Geckoo1337 says ...
Dec 22, 2016 @ 7:15am

Cool concept which could be improved. When the ball hit near the corner, I have no time to react. However, great project. Well done ++

panurge says ...
Dec 22, 2016 @ 11:38am

Okay, I was terrible at this! I kept forgetting which key was which colour and getting confused between the next ball colour and the colour of my gun etc. There's quite a lot to take in and I don't do well under pressure!

However, that's all my problem, not yours. :) I did have fun playing and I really admired the concept, the controls and the style. Great work!

Dec 25, 2016 @ 10:28am

Pretty challenging game! Nice combination of gfx, sfx and music. Good job!

wowa_u says ...
Dec 26, 2016 @ 9:24am

Pretty cool concept and it's fun to play. But sometimes it's a bit too hard, especially to react if the ball is in the corner.

Jan 21, 2017 @ 8:20pm

Fun little game! I included it in my compilation video series of the Ludum Dare 37 games, if you’d like to take a look. :)
