This is all good feedback, I agree with most. The music stopping is on purpose ("ops, you're dead, epicness is gone") but I guess I can make it start again where it was. Horse has some clip-clop sounds but the music is too loud, I'll add separated music/sfx sliders and more SFX is general.
I'm planning on expanding the game yeah, more level layouts with their own patterns, unlockables, integrated leaderboards and some other things
