Beaten it a few times now, tried runs with each of the weapons and genuinely the game seems fairly well balanced (outside of the secret knife ability which 3-shots the tardigrades and has plenty of startup and endlag, but It's supposed to be a crutch anyway, perhaps a fun challenge run? I'm pretty sure I've found the best 2 weapons in the game, being the shotgun and the Katana, with some optimising I cleared it in less than 2 minutes which I can send to you should you wish, might be a world record, although definitely a beatable one, made some execution mistakes. Makes for a fun speed game and hearing "DEFEND THIS POSITION" a bunch of times got a good laugh.
Especially for a game made in 25 hours it's quite a neat product, I think there may have been a couple oversight, my first sub-3 minute katana-only run involved swimming around in the water which I later found out by reading the floor is supposed to be acid, but that's to be expected for a short dev time and doesn't dampen the experience at all, if anything it enhances the ludonarrative of the character going to whatever lengths to stop the tardigrades.
Good stuff!
