The idea is interesting, but also to polish and polish:

• if you come up in a colored wall (for example, red), but a different color (white) is chosen, you do not pass, while if you choose the right one (red), you need to move away from the wall in order to still pass;
• if you change the color while on a colored wall, then everything is stuck, even if you switch to the correct color;
• you get stuck in the store, I don't know how to get away from it after the purchase;
• enemies will strike exactly, it is easier to run away from them than to fight;
• when you restart, the living standards are replenished completely, bought a bunch in the store, got stuck, restart and you have full lives (newly purchased ones too);
• but on the boss I had only 3 lives, although I came there from 7-8.
• the music is not good in my opinion;
• it is not clear where the exit to another level is (where you rest against the edge of the screen, and somewhere you pass);

All this makes it difficult to enjoy the game.

Good luck in development =)

the music is insane and I like it, I was a little confused of what to do in the second room, I read your comment bellow and now I got it, nice entry! 

Nice! I can tell you all put some effort into this! Great work! My biggest gripe is probably the collisions. Too often I got stuck in walls. I like the idea of switching the colors around to get to certain areas, although I wish I could just collect and keep colors instead of starting each new level with no colors. I got to the little room where there are a ton of suits of armor guys but Idk how you are supposed to beat them!? One suggestion I would say is to use knockback when I hit an enemy. As it is now, I can hit them with my paintbrush but they are still in full charge towards me!

Overall keep it up! The most fun I had was the level with red, blue, yellow, green and purple. The reason being I just tried to run as fast from one end to the other without stopping while changing colors as I got close to the bricks! haha. Great work though! :D

I like the effort put into the details and your game idea of switching colors sounds interesting! However, I got stuck at the area with 2nd treasure chest, am I supposed to jump or do something over the wall with the lava cracks? Hitting it didn't seem to work. Looking forward to see more :)
