The game feel is excellent in this one! Using the portals was a nice idea, too. I like difficult platformers, but it was a ~little~ bit too precise here, felt unfairly difficult at a few points. It took me more than 200 deaths to beat, a large chunk of them from trying to hit the very last trampoline. I also got stuck inside the wall at that point: 
The graphics and audio are good, the main character reminds me of the game "Forager". I really wish the character would move with the platforms though, it was a bit tedious having to keep tapping left/right to stay on it. I would have preferred to use portals with some other key, like Z or K. Nitpicks aside, it's very well made jam game!
