I found another one: When you enter the car the map direction is not switched to the car's direction so I traveled to the left or right on my minimap when moving forward.
The turret hit me several times, because it starts shooting before aiming. The car accelerates not properly when hitting the key (at least after reversed movement). Also I could drive under water and making the car tumble down a mountain. The car got reseted afterwards. My point is you could add a car health. The last point is, that monsters seem to spawn out of thin air right next to you and bite/shoot you. I leave it to you to change it or not, those are just some ideas I had. I like this game. :)
I just found a bug. You can click on the mummy repeatedly to get several bones as long as you do not remove your glasses. I thought lots of bones could be useful. The problem is, that this covered my inventory and I was not able to use items I found later in the game.
