Great to hear.
As good as the AI is, I also noticed that Marco often just stands around doing nothing, sometimes for such a long time that I low-key start to think the game just soft-locked.
Aside from that, the lack of enemies and shorter levels didn't really bother me as much, though I can definitely see that being a turnoff for some.
EDIT: I also noticed that the Marco bros can legit fire on you while paused, and the music will sometimes just stop playing. It's still a great game, especially given that you only had 10 days to make this; it's just something to keep in mind.
