Wow, Thank you for your time and feedback!
In fact, it would have been great if there had been a tutorial. especially because of the gadgets / extra moves that are not directly obvious. The level of difficulty actually depends a lot on chance. I had adjusted this again so that the most difficult enemies appear less often at the beginning, but from level 10 or so there should also be cameras and elite guards (the ones with a cone detection and instant movement) that at least increase the difficulty a little. But i have to be honest, that i did not playtest it long enough. I was aware that the difficulty is somewhat odd but not in which direction.
All in all i really appreciate your effort in playing my entry and your detailed feedback.
