I enjoyed this game way more than I anticipated. I was confused about the controls at first but I came to like it more than using the mouse (+my left hand is somewhat injured so just tapping shift made it helpful lol). The idea is presented clearly, does not want to over-complicate itself and is a very consistent overall.
I saw the end of the map and went full on to see if I would leave the area and I did fall (something I suffered a lot in my game especially clipping through unexpected movement) and I feel a constraint like that would make that players not end their runs unexpectedly.
