It's a very good game but there were a few gameplay aspects that felt a bit counter-intuitive to me:
- When the gravity changes my view of the room doesn't flip. My character(?) does flip and controls stay the same. That results in left arrow being "go right" and right arrow being "go left" when the square is upside (wherever its up is) down.
- The game description states that flipping gravity "will allow you to see things, other way hidden" but it's more like allowing to collect things other way intangible. Also, at first glance, the triangles seem more tangible than those color-distorted square groups.
- I feel that background music got louder over playtime (or as I collected more collectibles) but that might be just an illusion.
