Hey! Great job, i really like the concept for this and I think there is a lot you can do with the idea. A complaint I have though is that the jump is so fast that it is really difficult to switch colors in mid air. I got stuck on level 4 at the bottom level. I knew what i was supposed to do but the time frame to swap at the bottom was to difficult and the safe area in the middle was too small. Also, I think the control lay out could be a little different though that's not a big deal. Also maybe a color wheel at the top of the screen to show what order the colors are in because I kept forgetting but also that might just be part of the game.
I really like what you have and I hope you continue with this!
I've had a go at your game and finished it!
Scholley is right about the jumping, its a bit too fast. And remember what orders the colors were in was a problem for me as well.
The grass that kills you if your the wrong color felt a bit brutal, not that the idea is bad, just that it seemed like even if the tip of my slime was over it when i changed color i died. Should be an easy adjustment by just resizing the hitbox I would think.
As far as the boss goes, I think it should have a more predictable color change pattern.
I beat it, but i felt like in the final hp point, where he flickers the fastest, I got through it from luck rather than skill. Also I think it would be cool if the boss stage required some kind of jumping as well.
I don't mean to be too negative however, as the idea is quite interesting.
The graphics, sound effects and music are all quite good!
Good luck with further developing your game! :)
