I like the idea being displayed here, there's just a few issues that I experienced:
- unforgiving platforming (could be fixed with a little bit of "coyote time" after ledges)
- secret vision was spammable (felt like the ability should've been disabled when player inputs a movement key so that they have to stop in order to use it again)
- ball sometimes didn't respawn at end
For a game that only took 12 hours to make, it's very impressive. I imagine that, with another 4 hours, the game would've had more polish and be even better!
