I'd say this rather than superliminal, this feels more like Antichamber instead. Same kind of illogical puzzles, which are actually quite fun when you finally figure out what needs to be done. As you said, the game is short, but quite satisfying to complete. Best puzzle for me is definitely the do not press one, but some others are good as well. The worst for me is the this way up one, which feels really hard to get the cube to the correct orientation without any rotation at all. But anyway, this is quite a nicely done game!
Other things I like:
- Simple and clear graphics
- Sensitivity settings
- Shout out to the clever use of EmbedBG on the itch page
Suggestions:
- Pure white harms the eye a bit after watching for too long. Consider dimming it down a bit
- zooming in and out puzzle causes huge headache (physically) when zooming in too much. Not sure how to fix that though
