10/10 on the spooky. The use of audio really immersed me in the settings. Reminded me of Limbo! Will say I'm the worst at platformers, had a lot of difficulties completing the mine cart section. I loved the balls though! The sound they made had that crunch that tickled my ear.
The only critique I could maybe give would be about them controls. I'm more of an "AD left and right" kind of guy (versus the current QD). It definitely took to getting used to. Also, with the way my hands rested on my keyboard, I found myself shifting my pinkie comfortably to that L-Shift key versus the L-CTRL. Honestly though, to each their own (we all got our key binding preferences). I enjoyed playing it :)
