I'll keep those points in mind, the AI just checks if you are within a certain distance, it dosent raycast or anything, but its bullets dont go through walls so that shouldnt be a problem. I'm fixing the audio amd thinking of music as a possible update for the game, as well as a win condition. The idea of the theme is that each new try is a new dungeon and a new character, and thus a new beggining but admitedly the character selection is lacking. I'm adding a way to select a character, the weapon amd even maybe a power of some sort to create more varied builds. Thanks for checking it out and taking the time to point these things out!
btw you cannot kill the ghost enemy, he is there to add pressure and force you to move quickly through the dungeon.
