As other commenters have said, the cooldown between guns infringes on the flow of action which is a shame for an action game. The fact that you also have time to prepare for your gun completely breaks the "out of control aspect". Apart from that, gameplay is pretty smooth, with simple controls and clear objective. Id say that the colliders on some of the bullets are kind of small but apart from that it's alright. Also, not much room for the slowdown mechanic, I barely used it. Could be nice to have music to pump the action up, because the sound effects on their own sound a bit empty. The art is fine, and I appreciate that cheeky Sans easter egg at the bottom right hehe.
