As others already mentioned it, really cool idea to combine the genres to create something new.
However, your game has some flaws, which I would like to explain here to help you improve on it:
- I assume that you have used the normal Text GameObject for the WASD, because the resolution is super bad. Please ignore the Text GameObject and use the TextMeshPro for everything instead. Super crisp fonts at all sizes ;)
- Why did you decide to take WASD as controls? I just couldn't wrap my hand around the weird positioning of the keys in a straight line. It would have been nice if you took 4 keys that are next to eachother so that the player has an easier time pressing the right key. Ignoring the theme on that part, because messing with the control scheme too much is just annoying and frustrating. ASDF would have been really nice as keys.
- The start of the game was a little weird because most of the time it directly showed game over for me. I just had to try a few times until the game started, then it was ok.
- Are the buttons prompts in any relation to the music or are they mostly arranged randomly? Because I couldn't really find a pattern and that is very important for a rythm based game. Maybe it's just me.
I hope my feedback can help you.
