The vibe was really good, sound design worked great! I liked the concept of the wheel, but I felt the execution wasn't super good. More specifically, the random effects really didn't change anything at all for me, fast or slow, inverted or normal, I wasn't more challenged because of them (in fact, I didn't even notice the changes until like the third round).
The color switching however, that I thought worked! It kept me on my toes, forced me to focus, and made it more stressful knowing it might change (which is good because it's a horror game). It could've used some secondary identifier though, like an effect, sound, or a slightly distorted symbol.
Also the wheel sometimes moved by itself, which was weird. And it's a shame you couldn't get fullscreen to work, it felt really wonky (the window even moved around in my browser during the intro cutscene)
Overall, great work! It's a very unique and cool game!
