Neat and novel concept. I think it would have been way too hard if you were actually able to die with the current amount of firing the boss does lol. Would be nice to have the main death part actually in the game but a good start

i like the idea of the gameplay, i think it's quite unique. the key part was missing haha but it's alright, i think the vision is still there even tho it would be much better. i like that the boss doesn't shoot until the character is moving but i'm not sure if it was your intention to trigger it with mouse movement also.
