Just lovely. Baba Is You gives you a rush of satisfaction every time you crack one of its puzzles. But in a way, not unlike suddenly getting the punchline of a pun that went over your head. Not so much "aha!", but more like "haha!" if that makes any sense.

Thanks to its charm and quirkiness it never makes you feel stupid or puts the player down. Just lets you in on the joke you've been missing out on while tinkering with its mind-bending, rule-breaking, puzzles.
