Hi, thanks for playing! I've gone in and fixed some of the bugs you reported and made some adjustments to brightness and weapons. I'll work on performance, weapon damage falloff and audio for the next update. You can actually get into the underground section by shooting the wood planks and finish the level from there. I'm hoping as I add more destructibles to the game, stuff like this will be more intuitive. Since there are very few currently, I can definitely see how weird it is. Cheers for the feedback!
