I'm not sure how to win? It just gives me more objectives to kill more zombies? Overall, not bad for a simple game, just needs polishing and a map redo.

Honestly I had no idea what was going on here. Maybe my browser wasn't able to play it correctly?

I can still give some feedback though. When you clicked the mouse cursor stopped in place, not cool!

And if that is a store button in the top left, it also did not work for me.

Game is good, but I was kind of lost on where to go.  I don't know if boss was on the left side or just the text was being on displayed left. But considering time limit and theme it is good. It has potential.
