Deja vu
Hero shooting aliens with upgrades and leveling up? Gee, whats that remind me of...oh yeah the breach. That really upset me, it's exactly like it, but without atmosphere or interest. You opened really well with the plot which was amusing enough, however you managed to convince me the game didnt get anymore exciting past the 7th level, I didnt care about the guns, the diamonds seemed pointless (Yes, I'd like customizable guns/shields/abilities/looks but diamonds for some pointlessly powerful guns? You can keep them.) and I just felt myself wishing for a sequel to the breach through my brief playing.
Also, maybe you didnt realise but it was a "the breach"/Borderlands crossover supreme- A bandit sort of planet with a gunslinger with shields and the odd corrosive weapon. I'm surprised you didnt make electrical or incenditary weapons. Anyways, Great animation- poorly executed. Cmon Berzerk, you can do SO much better. Dont cloak your previous games in a different guise.
