OMG I loved this! I am such a fan of shortform weird games. The level of friction in letting the player figure things out for themselves was perfect for me. Good mix of puzzles. The decision to take the already low-res PICO-8 screen and draw yourself an *even smaller* screen to work with is also inspired. Also I did not know about the CRT filter in PICO-8 but I will look that up because it's a nice effect!
Favourite moment: turning into an L-shape!
My only complaint is that it was over so soon, shortform is great, but I would be down for about 2-3x longer before it would start to overstay I think. Would be cool to see more out of bounds weirdness towards the end.
