Woah, nice one Cakestorm!
You really managed to make a balanced progression curve here, no easy feat in a gamejam. The way you constrained the stylization gave you a lot of creative expression and cohesion with just a few strokes. Felt very hand built in the best way.
The mechanics feel rock solid, shooting and movement felt awesome, scooping up gold felt incredible and the UI was really beautiful
My only note is that I think slightly desaturating the debris and non-player allies could make it easier to pick out player and targets with your eyes. The screen got busy and a little trickier to visually parse towards the end of my play.
I wouldn't be at all surprised if this took first, it's a really polished and well stylized game, infinitely playable. Well done.
