Well done! This is the first game in Godot that I encountered here and it is quite good! Music is really great and sound effects as well!
As others said, aiming was a bit weird, where I'd need to aim down to actually hit enemies, and even then it could miss. The walking animation when aiming looks a little broken, but doesn't impact gameplay. Final thing is that while mashing my bullets on the final enemy, I immediately clicked the complete game button by accident. Then while trying to click it again to test (by mashing of course,) I glitched out the main menu where the game would let you move like in a real round, but the camera would be locked.
Minus these issues, it is a really great and fun entry! Really impressive having made all of that from scratch AND in Godot!
