Nicely done! The bouncing bullet ended up with me shooting myself in the face half the time, but at least it discouraged random firing, lol. Maybe there could've been some additional mechanic around that (e.g. the bullet gets stronger for every bounce or something like that). I also think it would've benefited from just free-form mouse aiming or something in that vein, now most of the challenge came from aiming.
Story was really nice, it's always fun when there's a jam game with a bit of a little something going on, so great job on that! The theme didn't maybe come through super strong (I guess explore the level to find the device, then find the exit portal), but that's all right, had fun anyway!
