Thanks for finding that bug! Originally we planned on doing a web version, however there was a horrible audio bug we could not reconcile before the deadline that made the audio sound like it was coming out of blown speakers (DAMN YOU HTML5!!) we do plan on releasing a web version at some point. We have updated the game since the jam, and we addressed the difficulty by adding health kits and checkpoints after every door. I Think that will help the difficulty, we also added input mapping so you can change and learn the controls and bumped the starting volume up a bit. Also i don't know if anyone noticed but we also have bullet drop! Because what modern shooter is complete without bullet physics?
Anyways, I'm glad you enjoyed it.
