your game is working nice, here is my feedback...
- great graphics, i love the vibe and attention to detail, runs smootly
- sometimes i was confused why i couldnt jump
- good sound effects
- the music is way too short of a loop and distracting
- a bit too much screen shake at the end, its ok to hit it with max screenshake when you die but it should stop after like a second
- more variety and progression as the game goes on would help keep players invested
