nice game, but the puzzles may need some polishing, i'm finding (probably) unintended solutions everywhere
for example, the second last level (which should be the one with the 4 spike jump), i didn't even use the flip at all... i just jumped across, and it isn't even difficult! plus you can die afterwards and the shard doesn't get put back into the starting position so once i get the shard i kill myself and get into the portal
really good polish though :)
