Really good submission! I thought the graphics and effects were really nice, especially the water effect and the gratuitous amount of blood splatter. It felt heavily inspired by Risk of Rain. I managed to make it to the boss at the end, but their flying form finished me off and I didn't have time to replay through it. The gun play felt a little repetitive, and the jumping was a bit buggy / imprecise. I also thought the theme interpretation was lacking, because the fact the gun was a "moon gun" didn't affect the gameplay at all. I think if you leaned into the rogue-like mechanics with procedural maps it could be very easily fleshed out into a full game.
