Yikes the graphics are bad. I dont even know when I am hitting the notes. Maybe put a small drum noise? There was not any button mapping either. The bare bones of this rhythm game is somewhat decent. Other than that you REALLY need to improve on the art. Maybe ask a friend? Im not sure how hard it is for you to get these things, but the songs are cool. I hope you keep working on this any improving. Good luck.

I have some suggestions:
Give some feedback as to whether or not I hit a note, half the time I couldn't tell what was going on because the line near the top of the screen just did nothing.
Make the level select a bit more readable too? It feels like everything is crammed together, and it doesn't help that the background of the previous level just stays there after finishing it which makes the level select even harder to read.
Also, try to make the level select easier to read in general, I don't see why the time signature is a necessary thing to put on the level select because it just takes up way too much space and it just looks like a jumble of text.
The tracks were pretty fucking sick though, I like the music choice.
Hope this wasn't too harsh, thanks!
