Solid work, the animations and feel of movement were great. The little bit of story and cutscenes were awesome to see. The cutscenes felt really high quality.
That being said there was a few issues I came across.
Biggest one is definitely the randomness and the consequence of being unlucky. I might be wrong but I could not find a way to tell what route was correct, so it was guessing, getting an unlucky guess was a slow death waiting for the hand to catch up (I did love the hand, a very cool enemy concept!). This on its own is kind of fine but has more issues because of the next thing.
It would be really nice to be able to skip the cutscene. Its a nice cutscene, but considering you see it after death every time.. well you kind of see it alot and it can be super annoying when you get a bad pattern and die instantly because the hand is moving super fast on level 8. So you watch it 2 times in a row and its not long but its also not instant so dying alot adds up. A game that excels in this area is hotline Miami, death is constant fast and the game is brutal and hard. But retrying the section is instantaneous.
those are honestly the only 2 kinda issues that arent just minor nitpicks or recommendations. You did well but these 2 things combined to make the later levels less fun.
I noticed the UI was behind the flooring, in unity it can help to give canvases their own layer ontop of everything.
Great work on the entry, but level 8 was a bit much (I did win but took me quite a while)
