Psy-Doge: Dog vs Grandpa 3D
«Psy-Doge: Dog vs Grandpa 3D» is a light arcade-style dog game about a mischievous pup who takes over the yard while running from an angry grandpa. You mark your territory and slowly turn the whole yard into your domain. The goal is to cover the entire location with your markings. Grandpa patrols the yard and does not like uninvited guests on his property. The more food you find, the larger the area you can mark in a single run. But a well-fed dog moves more slowly than a hungry one, so you have to stay alert while you race around the yard.
How to play?
Control your dog and run around the yard to mark the ground. Grab food to increase how much territory you can claim at once, but remember that a full dog moves more slowly than a hungry one. Grandpa constantly walks his route, and if he spots you, he starts chasing you. Use cover and weave between objects to break the line of sight. Watch your puppy's stats too. Stamina drops while you run, and if it hits zero, you lose. Take short breaks between sprints and look for food to restore your strength. Each snack you eat expands your marking radius, so plan your route ahead of time. Capture the entire yard before Grandpa catches you, then become the master of the territory and show the old man who really owns this place.
