I defeated M.A.C, ironically the one time I never could go to a shop.
The game looks super good. Controls also feels pretty good despite the lack of sounds due to the smoothness, low hps of the enemies, cool patterns and visual feedback. The boss fight is cool with the right length and difficulty, took me a few times to beat.
You get stuck when you move onto an arrow for the second time (and I never understood what it does the first time either).
The game is cool, thanks for sharing.
