Well it just crashed again for me (before going to buy-screen).

As I said some improvement suggestions:
- make duck/stand up faster
- let the player hold their breath in sniping mode for a short time, but increase breathing for some time afterwards. if the player holds his breath too long, maybe even reduce the HP or just go to very heavy breathing
I know that this might cause some advantage for snipers, but its worth a test I guess
- I could fire 3-bullet burst shots with the pistol. Is that intended?
- A re-configureable key setup would be nice
