I really like the tile set! the color contrast made the whole climb feel more intense! Excellent mechanic too. I was surprised by how many ways you put a spin on it, my favorite was freezing mid-air to jump between two walls! Some of the longer levels could do with a checkpoint part-way (mostly just the ones with the rotating blocks; they're uber neat, just a little slow). The TNT blocks, while having amazing visual/sound effects and showing off the physics nicely, feel a bit like like their from a more fast paced game (i had to flip flop between my puzzle genius brain and my platforming expert brain a couple times). Great level design, and the chill retro tunes tie it all together! :o)
