Thank you for the feedback! I really had to make it easier, but what can I say I like hard games. It's not for everyone I know, but with a lot of practice everyone could do it. (SPOILER ALERT) You can finish level 1 by being stealthy and that unlocks the achievement "the prey". Unlock all the achievements and that's the end of the game!. Only the play level 2 50 times achievement doesn't work, I'am fixing it today.
