Heya! Very fair feedback indeed. When it comes to the movement, I wasn't the one working on it but it was something that we've had a problem with since the very start, juggling between it feeling too stiff and being too slippery, and in the end we just didn't have enough time to balance it out properly. I completely agree with you on that. I did work on the parallax background logic, and I'm not satisfied with it either, but same as the movement, I just didn't have enough time to fix the issues I have with them. We decided the game should have 5 levels, each representing one area, for story reasons. I do take responsibility for the design of the final 3 levels however, and I do appreciate the feedback on the clues. We have been planning a little post-jam patch for the game and we should work on most of these issues! I'm sorry you felt sick!
