After a long time i've managed to focus on this game for a little bit and I'm now proud to announce this update!

Major changes:

-General gameplay overhaul
All weapon stats have been changed, all enemies have been updated as well. 
Everything is faster now and thanks to this the whole game feels more alive.

-New soundtrack
Since the core gameplay speed has changed, i decided to include a new soundtrack. All credits to AIRGLOW.

-Google play services integration
Now you can obtain up to 10 achievements.
You can also flex on your friends with your score on the leaderboard.

Minor changes:

-Optimisation
Random stuttering should no longer bother players.
More performance overall
Got rid of random lag spikes

-Finally added a pause button for phones without the "back" button

-Slightly fancier graphics
