Thank you for reporting this.
But I haven't checked it yet, but since you mentioned you like it, I'm not making changes to it for now.
Thank you!
In all fairness, while having this bullet time is indeed enjoyable on itself, it can be also exploited with some weapons.
For example, Focused Fan actually has a very low delay between shots, so if you can click really fast, you can unleash an enormous barrage of bullets at the enemy, allowing you to quickly deal with a threat at close range. While I'm not sure if it can be exploited by users with some sort of "Turbo" functionality that could emulate a high amount of button presses within short time, "bullet time" certainly allows you to spam Focused Fan, letting you to deal with an enemy faster on a game timer than you'd usually do it. This behaviour can probably also be experienced with other weapons that have short delay between shots, so there might be a need for making a choice of either keeping this gimmick despite spam potential (obvious drawback is amount of energy you'll spend on such barrage without reneg since you're in mid-air), re-balancing weapons (adding extra delay to weapons that haven't had it before) or removing the gimmick. I wish there was more feedback on it, that would certainly make it a bit easier to consider how many people even use that trick and how useful they find it to be.
