it's good as a short little game to play for like 5 - 10 minutes but doesn't strive much beyond that. the upgrades are quite good and fun, i actually like that a lot as it adds some progression. it also does fit the theme quite literally since you're spinning an object.
the point of the game is a little confusing. am i getting spins per second or am i getting how many spins I've done? i don't think this matters a lot and this is a minor criticism though.
the ui is quite good but visually i feel it could've been a bit more rewarding. the spinner could use more animations imo. the combo could also be a ui element, that would help a lot with making it more rewarding.
the music is a bit monotonous. the spinner itself could use some sound effects as well. i will give credit where credit is due though that hitting the green feels quite satisfying and is one of the best parts of the game.
