First of all, thank you for playing and leaving a comment!
About movement speed, problematic point, and i couldn't say that you're not right, it's just everyone's preferences, so i guess, should spend more time fine-tinung that variable!
Also about boxes, thought it's worst point of game, it was hard to find right word to describe task, especially when it isn't my native language! And maybe i could place last body part somewhere closer to them or light that boxes up more so they are more visible, but yea, think it could be done better!
About volume bug, will investigate what happens, didn't playtested the game much to find that problem, when i was developing the UI it was ok.
Overall, great comment on game, thank you!
