Ok first thing first, how on earth did you upload this mate? I nearly panicked after my 50mb game failed to upload 4 times in a row, and yours is almost ten times that! Granted I was trying to upload during a thunderstorm and my net was slower than usual, but still! :D
On to the game, it looks awesome! Controls feel like they could be a bit tighter, but it's perfectly ok as i t stands.
There are some clipping issues with the translucent walls though. Not sure if it was intentional.
Interactive objects need to be pointed at pretty precisely in order to trigger them . . . which could be streamlined with a crosshair i guess.
Finally, it's rather difficult to tell where the weapon will get reflected to next. I shot myself inadvertently a few times.
All in all, excellent game! I hope you take this further once the jam is done :)
Cheers!
