The mirror is a bit weird to control/aim with, but I like the Ikaruga mechanic you got going on here (being impervious to the bullet the same colour as you). Awesome soundtrack.

Gameplay is awesome - bullet time here is perfect! I survived for almost 2 minutes in 1st try, so I guess it's long, it was very hot! :D 

First I bit skeptical about this but the difficulty is really ramp up. I think you should vary the slow down time. For example:

• make it slower based on the total number of the bullets, or
• make it slower/faster when player near either laser or bullet

Nice take on the theme! At first it feels really unintuitive to move like this, but once you get the hang of it, it plays a lot better. you really see your high score increase the more you play it. If you plan on continuing updates, besides the lasers you could have powerups spawn in the field for some extra bonusses to keep the gameplay engaging :) Well done!
