I'm glad you enjoyed the game! I'm sorry to hear about the motion sickness - could you pinpoint what caused it? One thing that I'm aware of is that I like high mouse sensitivity and I ran out of time to make it configurable or at least set it to standard level.
The open-world aspect was an experimental choice for an adventure game, and although there are things I'd tweak now, time was a constraint. Additionally, this game (the same exec) is compatible with (PC)VR, which is another facet of this experiment.
It's encouraging to hear positive feedback from a German player! :) Especially since I'm not fluent in German apart from just a few phrases :) Your opinion is truly valuable to me! Did you have an opportunity to finish the game? I'm curious whether the puzzles were too easy or hard, and if they were engaging and how much time it took to finish the game.
Can you also tell me what was the biggest surprise? :)
Thank you very much for your feedback!
