Good Concept.
Fix collision boxes.

Nice :)

I think a mute button would go a long way.

Collisions are loose, not precise and makes it a little unfair but the overall game is really basic. No sound at all to speak of on this end.

In the future you should export this as a single exe, not an installer, because it's really troublesome to uninstall these and go through the install process for a micro game like this. Still, if this is your first project it's a pretty good effort, feels like it needed a bit more focus on the project and a lil more polish to get a bit more to it.

Nice twist on a classic two button game. I like how you have different worlds and each world has a bit different gameplay. The hitboxes of the obstacles are a bit big. I lost several hearts, even though I clearly would have missed the obstacle.

I didn't hear any sound. I assume there should be if I can vote on audio?
