It is not too late to fix the tiny font. Itch has the option to add a "full-screen" button to your game. The image above was captured at native resolution, if it was blown up to FHD I might be able to read the buttons, which I believe say "play" then "quit".
We have a rhythm game here. I like the clear display of what is coming and what has passed. One of the beeps the keys press is topping out, and I think that makes it sound harsh. You should add some more lore. What is everyone doing here? It feels like it wants to be subway surfer.
