Hey, I'm so sorry to hear that. The second level is where the player is first able to receive the revolver; it is on the table. From that level onwards, other weapons can be found.
Thank you for your feedback. I'll be sure to make it so enemies drop their guns instead of ammo in the future.
Thank you! About the wall textures, there was, but with the way the tilemap and player vision cone was set up, it was creating shadows over the buildings where the player's vision collided with a wall. It was one of those things that I was unable to find a solution for in time.
