UP! with a stranger

The first co-op game made for strangers. Go UP! as two plasticine blobs tied by a string, from your backyard to space and beyond. Find out how high you can get, the only rule: don't let the string break!

Why I made it

Wanted to make a game my entire life. Vibejam and levelsio's twitter activity was the push. The look is a love letter to my childhood games, originally described as: this is what you'd get if Purple & Brown, It Takes Two, and Flappy Bird had a kid. Coming from an art director background I also wanted to see if AI-built work could feel like it wasn't, full of charm, weird little details and love. First game I've ever shipped! 99% vibe coded! Dumb by design!
