Wow. This one took me by suprise in the greatest way!
Visuals: Loved the art style. Consistent and unique.
Audio: Fit the theme and vibe very well.
Gameplay: I liked how simple the games were. Possible add could be a slower versions of the games when it's your first time seeing it and then full speed later, but the current version works just fine.
Overall: Loved what was going on here and definitely kept me engaged until the end.
