Nice, vibey puzzle game, but I feel it often relied on luck rather than a consistent solution? The spinning spiked cube in the centre of the final yellow room for instance: My best way to get through just relied on holding Q and E and moving right along the wall and hoping I didn't get hit until eventually I made it through sheer number of attempts.
Not all puzzles are like this of course, but yes, quite the difficult game you've put together (ESPECIALLY with the fixed camera). Not necessarily a bad thing, but I feel it jumped in difficulty far too quickly.
