This is a really great concept! I really like the idea and with a bit of polish and some more content this could be a really great game.
I think my biggest issue is the "scroll speed" or the speed at which the arrows come is just a bit slow, you can see which is next (which is really great btw) but not knowing what comes after that makes hard mode unsight-readable which is a bit frustrating.
I really like the theming and take on "spin to win", this isn't a concept I've seen done before which is awesome!
Overall I had a pretty good time and I'd like to see this style of gameplay explored further!
