Pixurbia - Wild West Update Part 1

Grab a horse, your gun, and some new bugfixes in the latest Pixurbia update!

New content:

• Horses!!
• *New weapon* The Revolver

Horses spawn both at a fixed location (behind the buyable mansion) and out in nature. There is a new gun store added to the map that sells the revolver.

Getting ready to build some sort of Wild West mode or location. Not sure if I should just expand the current map and add a new countryside that uses horses, or if there should be an alternate start in this new setting.

New fixes:

• Selling a certain car no longer causes crash
• The east side bank's investment system now functions properly
• Multiple fixes related to the horses
