This games concept came mainly from the artists, who loved the fun of combining wild west themes with zombies. We liked the idea of gameplay changing as the character became more zombified and built off of that.

Most of my time on this went on system design, as levels were fairly simple to assemble thanks to the excellent Unity tools scripted by Christopher Robertson. This included the weapons used by the character. the enemy wave system and the zombification. I also worked on the UI and UX of the menus. 

I’d say my biggest challenge on this was making zombification impactful and fun. To follow the theme it made the most sense for the player to become weaker the more zombified they were (losing their shotgun and eventually losing their pistol too). This does motivate and reward the player for playing well but it is also extra punishing on mistakes, making it a slow but painful death once you lose the shotgun unless you get lucky with the humanity drops. 

I think the game is still relatively fun but looking at it now, I think I would work towards giving the player still good but more challenging tools when more zombified (e.g. a melee weapon that is riskier but effective at hitting enemies in multiple directions). The player would still get weaker, but its less punishing as the player is still capable of using their tools to fight their way to acquire humanity pick ups.
