Very chill music and puzzles! Only issue I had is that the controls said I should press 'X' to warp when it's actually 'Shift' on keyboard (I pressed X an embarrassing amount of times before figuring that out).
I kind of wished there was a little more, but I can understand if it must have felt like all ideas had been used by the last puzzle (given the time restriction).
Speaking of which, I got pichuun'd by warping into a bullet...maybe give Renko some invul frames when she does that?
