cool game, but seemed to have trouble with spawning new zombies?

The graphic is a bit too derivative of Minecraft & it might have been more interesting.

The graphics are very neutral, the zombies are very similar to the villagers and the items are also too reminiscent of Minecraft.
Some more feedback on the gameplay would be great. The night could be made darker than the day, and the damage inflicted by the zombies could maybe push the player back and/or give invincibility-frames?
