Nice idea, however zombies spawning in batches makes it unfun to play however its pretty fun :3. Also speed upgrade when???
Thanks for the feedback! Speed upgrade can be bought after you save a collective 5 civilians among your runs.Spawn batching will be investigated and updated before I go to bed to make it more...'fun.' Mwhahahaha
Update posted.
Fixed a UI issue in the game over screen, adjusted spawn method to feel more 'smooth' and offer a more constant difficulty that grows gradually.
