It looks like it'll become a good game. My two cents are that when you're in the natural world at the beginning, I tend to prefer having a keyboard button to attack instead of mouse button to attack, unless the attack is targeted toward the mouse cursor which would make binding to the mouse button more appropriate. Once I was in the rift, getting LMB to control the movable platforms was sort of hit-or-miss and I would often just have the player attack instead of grabbing a platform to move. The very first one messed me up because it swapped the platform opacity when I moved it all the way down to jump on it -- I'm not sure if that's even intentional or a bug but it's very unintuitive and unnatural feeling. It was also a little unintuitive that you could only move the movable blocks while they're transparent but not when they're solid, and I'm not completely sure if that's a bug or a feature (it would be fine to keep as a feature if intended). I could get through the rift until I reached a point where there were two back-to-back vertically moving blocks with the same start and end y-coordinates and I couldn't manage to grab and move either of them (most of the time when I tried clicking on them the player attacked, but I could occasionally click on them and have the player not attack but was still not able to move the blocks afterward), so I stopped at that point.
