A pretty nice hack!
This was pretty short but fun. Maybe a bit empty at times, but it was generally very fun. I don't have much to complain about the level design other than that - it would have been nice to block the player from sometimes being able to go through slopes, but it's not major.
Aesthetically, while pretty good usually, it had some issues. A island was cutoff - while this one may not be very noticeable, there's a more noticeable issue too: the title screen movements recording patch wasn't uninstalled, resulting in glitchy events.
However, as there isn't much that really ruins the hack, I think a 4/5 would be fair.
