Stunning amount of content in there for a weekend jam game! The concept is really fun and the presentation is amusing. Only problems are a general lack of sound effects and a few bugs. For instance, I've done the brown dragon battle twice now (usually killing it instantly with my ridiculous arsenal) and the game seems to just get stuck there. Nothing happens, and when I go right it doesn't seem to proceed or go to an ending or anything. I'm also a little unclear on what gives you upgrade orbs besides grabbing the ones lying around. Still, very cool overall.
Also you have good taste in video game covers, I've been listening to that particular one on Spotify for years.
