Overall a pretty good game, especially for an alpha. Still some room for improvement, but that's what alphas are for. Some ideas :
1 : moving speed upgrade isn't particularly needed, could be replaced.
2 : shooting range should be limited (a new upgrade ?), especially for shotgun to prevent you to splatter the house from a fixed point.
3 : the light could be only semi-circular, and upgradable, for example 90° at starting point, enhanced to 180° and then 270° (won't see in your back)
So much in awe this game left me,
I'll try to respond poetically :
I just wanted to say O dear Lenore
I never knew a girl like you befoooooore !

Hey, at first I thought "How awesome are these puns !" Then I was axe-ing myself ,"and in french? "('cause I'm French, you non-frog-eating gang :) And I was dis-axe-pointed... But then I read "vas te faire paix-tre.". Grammatical-error free (no -s to "va"), that made my day !
