This game is really cool! It is very similar to a concept that our team was working on, we never got that far but I'm thrilled that you made it work this well.
The color idea, combining different actions and painting them onto the tiles, reads really well, allows for some interesting gameplay, and is a great foundation for adding more and more complex actions and interactions. It's interesting how the game is presented like a platformer but the gameplay consists of problem-solving, though I feel like the character resetting upon any interaction with the environment kind of disrupts the gameplay and adds very little in return. In my opinion, it would have been better to either have the player start the character movement with a button, or just let the player interact with the environment while the character is moving and design the challenges to require faster reactions and more creativity, depending on which type of challenge you want to create.
But this game is lovely, very polished, easy to understand, and the music is really cool too!
