I have no idea what I'm supposed to be doing
Once I figured it out, it's actually a pretty neat concept, but this game really falls into the category of things that need a manual but don't have one.
One thing that really blocked my attempts to understand this game is that the collision detection is a little off, and bouncing off the triangular platforms didn't happen consistently until I was actively aiming for them. Because of this, it took me a long time to figure out that this was the platforming mechanic mentioned.
I don't think the "crashing" sound, which sounds like something that would play if you messed up, helps either.
All the indicators on the right actually do correspond to something in the game, but I didn't figure out what everything meant for a while even after I'd figured out the basic mechanics. I'm not sure why these are so unintuitive; unlike the platforming part I can't put my finger on it.
Maybe the confusion is meant to be part of the experience, but I'm just not on board with that. I almost gave up after my first try before reluctantly trying again.
I do really like the (pseudo?) 3D graphics, and the soundtrack matches well. There's not a lot here in terms of variety, but what is there is quality and used well.
I still don't understand what I'm bouncing at or why I'm bouncing, but this is described as more or less a mechanics prototype, so that's probably besides the point.
