This is probably one of my favorite games that I've played during the jam thus far, honestly! The graphics and animations are gorgeous and clearly have a lot of time and love put into them, the different guns have such variety that it's a blast (pun intended) messing around with them, and once you get a feel for the controls, you can start dodging and weaving through enemy attacks and get out of confrontations without much of a scratch. I also really love the shopkeeper and how charmingly dorky he is.
One thing I will say I noticed, that I had a bit of an issue with, was the shop. I would put my cursor over a gun I wanted to buy, and for some reason the game kept registering me as buying another gun that I wasn't on. I'm not sure why this was, but it led to me buying a bazooka when I was trying to buy something smaller, for instance. It was fun to blast my way through the level, but I sort of wished I had been able to save it for another, harder level.
I had a really fun time with this one, and think you all did a wonderful job, especially given all of this was put together in the span of a week!
