Absolutely love the groovy music through the game, and your sound effects in general, they add a lot of life to the game.
It took a second to work out how the game worked, but once I did it was a really neat little game that felt right on theme. Your tutorial is not especially clear, and I didn’t realise straight away that the direction the finger points in is the next button to press to keep spinning. (I also didn’t realise that you could move in the tutorial; that might just be a me issue though).
As a small note, while I didn’t have the dexterity to do it myself I think it’s possible to win without moving at all by just building up an absurdly long spin and maintaining it; this strategy enabled me to get my best score. Speaking of difficulty I found it to be a challenge to just maintain the spin, let alone also moving around and processing everything else that was going on, so just something to keep in mind.
The feel of the game as you hit enemies with the briefcase felt solid, and meant there was a lot of pressure and reason to keep the spins up; if I’m not mistaken each time an enemy took a hit you lose a small amount of momentum. The game has so much juice which is awesome, I just wish it was a bit easier.
