Good game, just very janky. There are a few glitches, all mainly to do with the walls and wall collision. For example, there was one where I basically climbed a wall to skip a lot of the level (too bad I fell back down).
However, the idea is a cool one, as well as the visuals being some of the best i've seen in the jam.
unfortunately, the unpredictable wall jumps, as well as the even more unpredictable physics of the blocks bring this down for me. Still though, great game.
