The game is a really good concept and the execution was amazing as well! I love tetris and this is surprisingly great twist on it, maybe add different sized grids to try because I felt this one is a bit too big, but again you probably have a good reason for making it this big
Really well polished incremental game, Great job! loved how i had to think about which upgrades i should prioritize at the start more, felt like it had some strategy to it
