Okay, good shit. Love the transition from "normal" music to "rage" one. Movement speed felt a bit too slow until I discovered the dash. Dash is fantastic, but it also makes me fall off the edges too often. Maybe a bit more walking speed would help?
I unironically think huge fuckoff gun models are great, I feel they provide a certain unhinge-ness to the game. But the bullets hurt my eyes. I kinda don't mind the travel time, but it feels just a bit too slow. It's very noticeable if you use a shotgun - the time between the shot and the hit is VERY high.
Shotgun seems broken - it locked out on me multiple times (I could no longer shoot). Guns and SMGs are fun, so is the minigun - though I kinda don't see the distinction between the minigun and SMGs.
Shitting out the grenade instead of throwing it is also a weird decision.
But I had a lot of fun. I really, really dig your demo - looking forward for more next DD!
