I noticed the textures aren't sharp. You can change that if you go into the texture asset and change change the filter mode from "Bilinear" to "Point (no filter)".
The way you experimented with different genres was interesting. I could see how one could make a separate game for each one.
I couldn't get behind the rhythm, drums felt too bland and I myself was mostly ferociously clicking to get to the next safe spot before it is too late. I only finished the game since I was told that there are only three levels with different themes.
The green color of the grass in the second level was too saturated. You should tone it down by a notch.
