The tutorial is good, but the first level starts you off on that very difficult bounce, so you're replaying that section a lot and it got frustrating. Also, I think it's impossible to reach the "bounce" platform without gaining momentum. There were multiple times where I didn't get enough and died a centimeter away from it. EDIT: Looking back, I got too much momentum and shot past the platform before, that was the timing issue, but it wasn't that bad.
After getting into a rhythm it's easy to get to, but then I have to let go off spacebar and left key, otherwise I feel like it doesn't register down X, but the timing is too demanding for me to get it right. Without momentum, I found it impossible to make the bounce. A few times I made the bounce, but I fumbled the controls or didn't get into the orbit electricity, so on and so forth. Probably spent 5-10 minutes on that bounce yesterday.
I'm just bad at it. A speedrunner, though, could probably make easy work of it!
