So Steampipe is way more complicated than I ever thought it would be. I was used to itch.io, where you just click upload and choose a file. Anyway, I finally got it online and now I have to wait 2-5 business days for approval. You can always go to itch, but you need Paypal, and Paypal sucks.
Thanks for putting up with my n00bness with Steam (I never use it). While I'm waiting, I'll make some short challenge story files to show off how easy it is to mod this game.
