while I think that's a cool system, I didn't actually even know that. you should have something to tell you about things like strafing, how to (s)lay the dragon. (you might have, I'm not sure cuz I didn't read very much but I clicked quite a few of the orbs so I am not sure.) yet again, I love the game and even then, its still fun and challenging. also having the menu pause the game would be nice as I had to die once from needing to quickly get up and do something.
There's a vague hint about how to beat the boss in one of the glowing orb thingies that gives you flavor text. It's quite cryptic though and the whole boss mechanic (and the game in general, being a game jam game) is a bit of a hasty job overall, I was kind of learning as I was building the game, so the whole game is pretty much just trial and error from start to finish. Lots of overlooked stuff and missing basic features.
