Wow, this was really well made! It was so fun coming up with different synergies with upgrades! You are really good at game design! Almost everything about his game feels very thought-out! It is so satisfying to attack with a lot of tiles at once, and the upgrades were all very interesting! I especially liked that most of them could only be used on one color!
I would appreciate some feedback on my game, since I haven't gotten much at the moment: https://itch.io/jam/game-off-2025/rate/4075824
