Quite playful and charming, with some cool "classic" level design and neat gimmicks. Having gotten all the special coins, I think some of them are placed in some player-antagonistic ways [i.e. using a bonus pipe that doesn't have any of the coins, then being placed past where one might be] so I found myself replaying levels I wouldn't necessarily otherwise. But it's super cute so I didn't mind too much, and as someone who likely wouldn't do too well with kaizo hacks it's nice to see a more casual hack that's well put together.
