Utility mod: make enemy hitboxes take up as much room as there is.
penguin 12 May, 2023 @ 2:28pm 
Just updated a lot of the old things I put in here, I feel like there's a bit more fun and a bit more balanced now, I've been using the Card Creator to jot down ideas but I just remembered that I had posted this forever ago.

Anyway I might I'm gonna start posting in here again. (now to update all the busted bottle relics I made, lol)
penguin 12 May, 2023 @ 3:09pm 
Oinksy was a really unique idea, It would probably be cool for a standalone character rather than just a relic, a starter relic if you would (maybe a custom run modifier too, so you could play defect and start with her)
penguin 12 May, 2023 @ 3:11pm 
you could even have unique Oinksy cards that only she could get...

It's moments like this I wish I knew how to make StS mods
Mr.Manic 2 Nov, 2023 @ 2:15pm 
what about the shadow wizard money gang?
I need a mod that allows me to play the entire game with my keyboard. There's hotkeys, but it lacks some important things, like using potions, scrolling up and down and the ESC menu
