Fun!
I really liked the weapon mechanics; how you have an inaccurate weapon; then a long range; then long range with spread; then the minigun ... not sure if there is any after that?
Nice touch with the music fading in and out too; was thinking it'd be cool to have another song fade in while attacking after awhile to bring in some more intensity. I like the music that plays though!
The visuals are great too; it reminds me of a game called Disco Zoo. I think the sound chosen for beating the zombies added to this for me for some reason; it softens the whole theme of zombies in a fun way.
This was a great submission...I've rated 35 games in the jam so far and this is my favorite. :)
