That's right, you collect more weapons as you go, and they're all fully automatic. I've fixed the active shield now that negates damage while up, you might not have had that when you played (use spacebar!)
I really wanted to set up an 'active weapon' that targets where mouse so you can aim manually, and get an attack speed buff. I ran into a bunch of issues with it though, so im not sure if ill get time to finish it off before the deadline...
I think enemy projectiles were broken earlier too, they should actually hurt you now! :D
I'm doing a polish and balance pass now, I'll try and add these two features if i manage to eek out some time.
