I couldn't get super far in this game, but it's great! The gameplay loop has a great premise, and it makes me want to keep playing it over and over again. The artstyle is wonderful - I love the arcade-style layout with the instructions and extra visuals to the sides, and the three-color palette makes the game extremely readable and gives it an iconic theme.
My only critique is the issues with seeing the entire screen (it can be solved by fullscreening the game, as you mentioned in the description, but it would be nice if there was no issue by default).
