Hello!
I tried your game and I was really impressed - it was very fun! The graphics were nice and the time slowing portion was very cool. I also liked the background music and the difficultly at the higher levels.
Some things I think would improve the game would be to add a pause feature and to clean up some of the glitches. There was one where the time orb would appear and I would need to re-click to start firing again - it was inconsistent which made it a little bit more tricky.
The best moment was when I got to level 7 (or 8), and all of a sudden I got surrounded by 8 blade spinning guys - it was hilariously scary. Great job!
