Fun game!
The presentation of this game is definitely the best part, there is a lot of juice, but it's not super overdone, apart from the screenshake, which could definitely be toned down a few notches. The art was nice and creative, and I liked the glowy bits, also, the gif of the shotgun spinning is very I'd also like to point out that the game was stuck at a singular resolution with no scaling at all, to me it was just an inconvenience, but to somebody with a 4k or even 8k display, this could make the game borderline unplayable. Last thing I'd like to point out, is that the title is clever and cute.
The gameplay is actually really solid, just taking the shooting mechanics and the movement controller and plopping them into basically any other scenario would work really nicely [especially if you had to use the blanks' knockback to cross gaps or something]. As stated in others' comments, the biggest drawback of this game's gameplay is definitely the lack of variety, especially on the map front, as it gets boring pretty quickly, I ended up just running into the enemies at around 30 or 40 kills because I was getting bored. I wish there was a way to reload manually once you were at one shot, as it was a bit annoying to waste time firing a blank just to have a chance at a better shell.
Generally, I really enjoyed this game, even if I did have to end it myself, I feel like you could really just grab the mechanics of this game, create a few levels and make some enemy placements instead of a spawner and it would be like twice as good as it is now. Thanks for making this, and good luck in the jam!
