I love Enter the Gungeon, so by effect I had a lot of fun here.
The art was really smooth and the gameplay was well-executed as well. The guns looked a little samey and would’ve liked some variety in design. Shotgun may be a little overpowered as I stomped everyone as I went through. Also, occasionally an enemy would practically spawn on my character and I would take damage that I had no way of avoiding. A visual indicator for a little bit longer before they spawn would be great (I know you have that translucent effect that is a great indicator, maybe just another 0.2 seconds or something).
Some additional enemy variety would also be nice, but I understand the constraints of time for a jam.
Overall, great game!
