I'm following HeartBeast's great tutorial series to make a RPG, and making up my own assets as I go along. It's not impressive, but maybe someday it can be. I've only just started out, and have barely scratched the surface, but it's clear to me that so much can be done in GameMaker Studio. I haven't had this much fun making something in as long as I can remember. It's incredibly refreshing. I feel like a wizard, bringing little sprite monsters to life!
Here's my monsters walking around, and bumping into each other.
