What a nice idea. And quite polished too! The controls feel very satisfying since they automatically snap to the grid so you don't need to be too precise with your movement. Well done!
In the middle of the level, it did sometimes feel a bit boring if you don't have any good blocks around and are surrounded by wrong color or bombs. Makes me wish there was some sort of invincible/boost button that would allow me to quickly move to a different part of the map while ignoring other blocks for a short while.
By the way, it would make me happy if you gave feedback on our game too! https://lisyarus.itch.io/color-fractory
