Hey, thanks for playing!
The game was initially supposed to have full control of its window, but those functions were scrapped in a rather lazy manner, which may have resulted in the monitor thing.
I actually really wasn't a fan of the soundtrack (with the exception of the menu theme and the rendition of "LittleGame"), but I've heard it serves its purpose well anyway, so I guess it works!
The game is made in Scratch, so coyote time might be a little hard to implement (also I want the game to reflect the classics in every way it can, and they weren't that polished). I guess if I had a script that waited until the player was off the ground, then offset other checks such as jumping accordingly? I'd have to experiment with it.
Anyway, thanks again for trying it out! The game is meant to be played with prior experience from the first game, but it's a jam entry so I didn't really expect for everyone to hold to that recommendation.
