I had some controls issues at first but finally was able to play. It looks good although I would have loved a more consistent look (pixel art character, clean font, etc). It's a bit simple, it lacks a bit of fun in the controls, and more feedback (the first time I hit a spike I must admit I didn't know what happened, I didn't see it really well, the game just restarted)
But you still completed your game, and that's already something ! keep pushing !
