The game is pretty fun, a simple platform where bats are trying to kill us. I love the mecanic with the helmet that produces light and temporarily keeps them away.
However, I think you should have used other inputs, like the space bar would have been to jump and maybe the left click to use the lights, as it is more conventional and thus, less frustrating to play.
Anyways, nice work, hope you'll add more levels to it ! :)
