Game has interesting concept but I need to say that its level design is definitely too much frustrating - you often die because either you didn't see offscreen bullet, your time power depletes or since some turrets have targetting directly on player, with unexpected bullet. Game should have not only better indicators for offscreen bullets but also the turrets should be more fair for the player and their placement should be more free - definitely bullets should be slower to, so you have more control over the character when you don't use slowing time mechanic.
In terms of technical stuff - no bug discovered so that's good. Game maybe doesn't look that good with combining different artstyles but it passes. Like I mentioned, the level design needs a revision - it makes the gameplay actually the weakest part of the game. Still, congrats that you made the game in time, even if it needs quite some polish.
