My roommates and I sat down on the couch to play through some jam games, and we picked this one first. Instead of playing a bunch of jam games, we stayed up until two in the morning yelling, "ohhhh i got it gimme the keyboard" at each other. This was a blast from beginning to end. Really good work!
We gave up after trying level D4 for like an hour and a half.
My only feedback is that it's hard to tell the different elevation tiles apart. Maybe having some slight shadows between the levels or a slightly non-orthographic camera would help?
Oh, also, my roommates instructed me to tell you, "its better than stephen's sausage roll and void stranger put together".
