Is certainly a work in progress, am working on the inverted mouse option and controller support as we speak. Few other things planned for next update:
1. More Weapons- pistol, shotgun, rifles, rocket launcher, grenade launcher
2. Better ammo/reload system
3. Custom map of Spoonerville not the demomap of Synty Polygon Apocalypse
4. More maps
5. Collectibles
6. POI Points of Interest
