Was able to play through it regardless of the issue mentioned in the other comment (by using a private window). Very nice. Really like how it all works!
Personally the screen warping effect is a bit too strong for my liking but that's not game breaking or anything.
I feel like the quick flip shouldn't necessarily work on the flip that's going on at the moment. It took me a couple of times for that to happen to understand what was going on.
Demo is on the shorter side and the ending was quite abrupt which is a shame, because I wanted to play more!
I'll be wishlisting this on Steam for sure :)
A small tip (though not sure how big the effects of it are): I would suggest creating a game and company page on https://www.igdb.com I use this to keep track of upcoming games for all platforms that I want to play
