Played on Linux using Proton Exp, First off i notice no Settings Options on Menu screen or in-game, then i hear my Graphics Card screaming for mercy and running at 700 to 1000FPS, And as no settings exist i can not set V-Sync or Frame Limiter.

The Games Graphics so far are not good and look nothing like the screenshots on the store page, Sound is just okay. Game play is err not Great, Runs forward on it's own and all you do is shoot the gun or try dodging the Zombs. reminds me of a Game i played on my Android tablet that was much better then this.

Also while playing you can pick up ammo boxes, you can also do some simple side missions??, like shoot 2 Zombies, dodge 2 times, slide 1 time, etc, and once you run the distance marked on your screen at the bottom then you complete that round and win some gold coins, coins can be used to buy better Guns, etc, each section has about 5 levels and like mobile games you will be rated out of 3 Stars.

And last but not least as the game has no option to see the keys used or a tutorial, i list what i figured out so far.

q and e = dodge left/right.
f = slide.
space = jump.
a and d move left/right.
r = reload.
and mouse buttons to fire (1) and sight mode (2).

Nearly forgot but the only way to Quit the game is "ALT + F4" as it does not even have a Quit option on the Menu Screen.
