First of all the game should have a better tutorial:
It plays everytime you start the game.
It is shown in text format with a lot of infomation for someone who just picked up the game without knowing anything about it to remember.
When you finish the tutorial the game starts with no mercy to the poor guy who just learned how to play from a bad tutorial
There is no menu :
When you start the game puts you in the tutorial
Gameplay : The gameplay wasn't really that satisfying but I think it is that way because maybe I'm not really a fan of the genre but I see potential in it if new weapons are added etc
Note : It is just a prototype for now so we can't really judge the game until the full release
