Game Features

An original game inspired by “Only Up!” and “Chained Together,” with unique elements added!

Controls are super simple—just move and jump.

As the name “IN HARNESS” implies, the game is designed with a focus on cooperation.
Experience the warm feeling of “Helper’s High” when you save a friend!

Not good at action games? No problem!
If you fall, you’ll transform into a floating bubble and rise back up.
If a teammate touches your bubble, you’ll revive—so help each other out!

Use voice chat to tackle puzzle-like gimmicks together!
For example, hanging from or pulling each other with the harness,
or puzzles where the blocks you can touch change for each player.
Talk things through and solve the puzzles as a team!

Simple and cute graphics!
