Very cool platformer! I really enjoyed it. I got through about 6 or 7 levels I think, but got too frustrated haha, it's a very challenging game.
I love the core mechanic you did a great job.
My only feedback was that something feels a little off with the spikes. I feel like I am dying earlier than I should be. I think one of the main issue is the spikes killing you from the sides, which feels a little bit off.
Anyway great job, keep up the amazing work!
