Dev Here. Regarding Zombie Movement: We chose a common game play mechanic of: Player moves 2 spaces with wall collision, enemies move 1 space without wall collision. This is to make the zombies more aggressive and the game play more engaging. We DID test a version where the zombies used pathfinding and it did not test well in our beta phase. Due to the mixed response of this mechanic, we will look into a different movement mechanic for the zombies all together in future sequels. Thank you for your great responses! Hope you enjoy the game!
