Really cool game so far :D
Only got to 470 Score XD
There are 2 bugs though:
#1 the vertical fence pieces will lock your vertical movement, if you are too close (or horizontal movement at the T intersections)
#2 Zombies seem to spawn even where collisions are (eg. in fences, houses, the trees at the room border)
Yeah i'm aware of all those problems. I think I rushed getting a playable release out.
I plan on tearing it down and building the map up before I drop any of the objects. I'll then make sure the collisions are working correctly and the spawn is right. Currently it's random but I may try and make them appear from specific areas rather than anywhere they like!
Glad you enjoyed it and I plan on adding much more to this.
