Get Rekt (LD 42)

My entry for Ludem Dare 42.

Welcome to the world of Get Rekt.
Full of weapons and explosions and zombies.
Will you survive long enough to set the best high score.

You got 4 weapons which you can use to deal with these zombies but, watch out the game likes to change from time to time And, your space becomes more limited when more zombies come from these portals.

go and play until you get rekt of course.
