There's a lot of polished game here! Great presentation and game feel, super cute art and quite a bit of enemy variety! I like the take on a tile matching game, and being able to buy multiple powerups for each color is really fun to make a build with. I especially liked the one that reduced the spawn rate of the chosen color so you can focus on your more built colors. The story events with rewards between rounds are also really nice to mix it up.
I think my only feedback is that I didn't realize you could swap any two tiles, I spent a while thinking it was just tiles that were touching.
Awesome job!
