Obviously this is a practice game / work-in-progress, so I'm not going to address everything - no sense in telling you what you already know. There are two things I want to mention, though.
1. It would be nice to just go straight to the next level instead of getting sent back to the home screen
and 2. platformers where the whole level fits on a single screen need some difficulty to be compelling. This is just basic platforming - it literally took less than a minute to beat because there's no challenge, just basic mechanics.
2.5/5 stars because it's got multiple levels, it functions, and because you're willing to try making games and put yourself out there, and that's a cool thing to do.
