Hmm.. on web version i start drifting to the right after the first shot, but that issue is not there when the game is downloaded :)
To further go into the spinning theme, I think it would have been great to spend more time to the revolver bullets. Why the spin, if every bullet is great? What does spinning even mean as there are 6 Bullets shown, but I have way more equipped? The Art style is great, and the gameplay is solid, but the game is easy with its OP bullets and I feel that something like cursed bullets with a drawback also shown in the ammo would have made the spin more exciting, right now its more of a reload animation for me. Still for a week, a very great start!
