I liked the idea of capturing creatures to create a new ability, and having a shrink ray fits the theme in a very clever way. I do wish the keybinds were shown somewhere besides the keybinds menu, especially when I have to fully restart the game to get to the main menu and, by proxy, the keybind menu.
Exploration could have benefited from not blocking off areas with invisible walls, this led to a bit of confusion where I wasn’t sure where to go for a bit, not knowing that an invisible wall I had run into earlier had quietly disappeared at some point.
(And a bonus nitpick: the menu button sound is a bit ear-piercing; I would recommend turning it down or using a different sound in the future.)
