It’s a really well thought out idea, nicely implemented. The two bigger feedbacks are the differences in sprite scaling and the lag issue on later loops. Second can be solved with some kind of partioning system, and the first just takes time. You clearly had effort into the pixel-art, let it truly shine!
Also, give me a loop number/indicator!
Forgot please look into the sound issue, it was realy loud! :D
Highscore: 260!
Well done! Solid entry!
