Hey,
Nice start in game-dev!
Looks cute but i have some suggestions.
- The "slow" running speed is really slow. And it feels like running underwater rather than slowly running.
- Jumping does not always work. I died mostly because it did not registered my jump presses.
- Some enemies does not look like enemies.
- Related to previous one, i had to die couple times just to test if i should do something or not. For example the "bombs" looks like they are Pop Bumpers and they would boost me.
Lastly, it's probably on me but it did not went fullscreen on mac with chrome.
