August 24th-27th 2012 :: Theme: Evolution

by sPe - 48 Hour Compo Entry

"Flrrr" is short but not necessarily easy. Evolve by collecting colors and bringing life to your world. But beware, the colors on the floor will hurt you! Also the background (music) evolves while you journey forward. 32 colors is a reasonable amount. Can you beat this?

The game may seem very easy at the beginning, but spare your health ;). Controls and some explanations are shown ingame.

Few technical details:
* The game will use the resolution of the current main display.
* Use the "-windowed" argument to start a 800x600 window.
* Should run quite good on older computers. The fullscreen effects are not blindingly fast. Window mode even works on Atom CPUs/ION platform.
* On my 64bit Linux the 32bit version was not able to capture the mouse. Hope it works for you :/. Also there is a 64bit version for Linux.

// Updated the Linux binaries with the fixes for blocking issues on some systems. Apparently that's ok with the rules.
// (Old "may crash" version still available at
// There is a gameplay video available:

Known issue:
Score does not count beyond the 32 goal, probably no fix for that as it would change the initial behavior.
Guess that kills the "endgame" content :).
You can cheat and keep moving after death as long as you don't release the keys.

-Linux versions-
If the game crashes at the loading screen, there is a more recent version with some fixes available at

I enjoyed it! It's a bit hard to feel when you're going to collide or step out of the grid, you should try moving the camera closer to the ground.

The concept is really interesting! I liked the trippy visuals as well.

This is some trippy shit. You should put a seizure warning on this!

That said, I enjoyed it all the way to 32.

I collected 21 colors. The gameplay is basic but fun enough. I had problem with control since I have azerty keyboard and could not remap keyboard

uh sorry for the keys. Only thought of the common y/z and special character mismatches :/. Must have been quite painful to play that way. Will learn from that and at least check the arrow keys in addition, or store the configuration in some text file if there is no time for a working menu.

Liked the theme and the trippy visuals. I didn't really feel challenged in the game tho. Am i missing something or do you simply have to walk to the end, avoiding the other colours? Also i love the idea of the music evolving, but it can get very jarring very quickly. Nice job though!

can you add the newer copies of libc and libstdc++ into the download or static link them? you're using glibc_2.14 which requires gcc4.6 so without installing an entirley new toolchain or finding someone else to provide me those files for download on 64 bit i can't test. Nice to see I'm not the only one who used SDL2 this compo though.

Regarding the (apparently) imminent release of SDL2, I wasn't really motivated to look up all the API differences as I directly jumped into SDL2 for cross-platform OpenGL support.
Thanks for the report. I've looked into the issue quite extensively. Static linking is usually no feasible alternative as this brings a whole new universe of licensing issues with it. Also it seems that just shipping those files can bring several other compatibility issues with dlopen within SDL and the rest of the system. I uploaded a rebuilt binary and was able to go down to 2.13. 2.11 was available but would've implicated gcc-4.4 and I need proper c++11 support.. that could have been a problem. Here I have 2.16 (with gcc 4.7) so it seems that compatibility hasn't changed in the last releases. Please give it a try if you want.

I liked it. Nice colorswirls. Like the procedural music, although it gets less melodic when evolving.

I was able to run it using my personal SDL2 build from my toolchain with your copies of GLEW/alut/and physfs (my personal setup is right now gcc 4.5.3 w/ glibc 2.11 so i have all the c++11/0x support I need plus compatability to run on all distros)

Game is cool, mouse is WAY too fast though, i couldnt turn at all or i'd just spin out of control. Oftentimes the colors would spawn completely around the goal also so the game was essentially random as to whether you can keep going or not. I like the visuals, and the music to a point, but after 22 or 23 loops the music starts to lose harmony and sound like just clashing random noise

technically cool, interesting concept too. gameplay is not quite there yet imho. the main skill you are challenging here is navigation, i wish the player could more actively engage with the colorsplashes, creating passages or interact otherwise with the phenomenon.

Feel like entering some kind of world ,with all those trippy sensations

I like it but I can't play it for too long, it makes me a bit nauseous. :/

I liked the "clean" look of the background effect, it's very well done. I like the music at first but it gets to be a bit of a cacophony before long.

Next time, you may want to normalize your direction vector; I can move twice as fast in the diagonal directions. :)

I like this idea and it looks pretty when it gets evolving. I didn't get any sound though, playing the windows version. I really like the idea of evolving soundtrack and you're not wrong about it getting harder! Really fun when you have to rush between 2 growing colours to get to the end bit, maybe make this happen more by giving you a timer to get to the next colour?
