Incredible atmosphere, fantastic stylisation, awesome sound design -- all round a super fantastic work.
I want to play to beat it but I'm having a hard time figuring out where I'm going wrong! Sometimes its felt like I've done all the tasks I can see but my heart rate is rising anyway. Some kind of post-game indication of what I failed at would be super helpful and make me want to grind at the game.
The spinning felt a touch off for me too, though I might just be bad; I could also never quite figure out whether the valve wanted to be rotated clockwise or anticlockwise, haha. Maybe you could just take the absolute value of the Mouse X & Y Input axes and automatically translate it to the valve rotation -- I think if you were to multiply it down enough and bound the mouse to the window, spinning would be the optimal strat anyway (as just going in a single direction would have your mouse hit the windows bounds).
A real pleasure to play -- excellent work!
