Super fun, I love the DOS-like/Windows 3.1 interface. The level design gives me a similar era vibe with a bit of Mario 2 in there as well. One of my thoughts was that the game runs suuuuper quick, like I'm fast forwarding in an emulator which makes it tough to play. Otherwise, very charming and cute and I hope to see it further along in the future.
Also the default control scheme is a bit awkward but I get that it's because it's for multiple people on one keyboard.
