I like the idea of a rhythm based infinite runner. I think the jumping could be adjusted to be a bit less floaty but It's a good game.
I did notice the spikes would often disappear but it didn't seem to be an issue.
the spikes disappear when you jump by the beat thats how it connects to the theme "every jump by the beat the spikes disappear"
thanks for your feedback
Oh I see, I hadn't noticed that.
