Crypt Of The Necrodancer is a rhythm based roguelike game. Basically, you kill monsters and collect loot while keeping to a beat. The game has some overlap with HATPC (caves, similar treasure chests, monkeys, floating skulls, etc.), and I read that it's really easy to make custom sprites for the game (especially since the
default sprite already kinda looks like Hannah). So I did my best to make a Hannah sprite, and then make a HATPCish level. It's got treasure, crates, skulls, skeletons, a monkey, an extra life, a gem, water, a ghost, and a
surprise Armin cameo. The game has no bird enemies whatsoever, so bats were the closest thing
I did take some liberties with how the game is actually played to make things more HATPCish. You can kill any enemy, but Hannah cannot, so I decided to go the pacifist route. Also the ice blocking the door could've been blown up with a bomb you get in your starting inventory of every level, but that wouldn't have been very interesting. Unlike HATPC, wooden crates cannot be broken unless you use explosives or a really strong shovel, so I could only push them around. The reason I did all the shuffling was since I wasn't killing any monsters, I needed the room to outmaneuver them once I reopened the door. Ideally, all the treasure chests would've contained gold, but AFAIK there's no way to control what loot you get from them.
In theory you could reskin the entire game as HATPC-themed if you edited more sprites, but just making a Hannah one tested my patience, and I cheated by not making any for various status effects the character would not encounter in my level. I admit the vid is kinda slapdash-- I came up with the idea, made the sprite, made the level, filmed it, and edited it all in one evening, but it wasn't exactly something I wanted to sink a bunch of time into
