Build Up!! vs Tether

Build your structure as high as you can! Gather additional building nodes along the way and reach the checkpoints!

You control two orbs. They're connected by a stretchy, springy tether. Drag one, and the other gets pulled along for the ride — whether it likes it or not. Both orbs need to reach their exits. Sounds simple. It is not. The tether isn't just connecting them — it's your secret weapon. Wrap it around pegs. Slingshot an orb around corners. Use tension, leverage, and a little creative chaos to solve increasingly devious mazes. WHAT MAKES IT DIFFERENT Most puzzle games give you buttons. Tether gives you physics. The elastic connection between your orbs creates emergent solutions — there's no single "right answer." Wrap, stretch, fling, and occasionally panic. GRAB A FRIEND (OR AN ENEMY) Hand your friend a phone. In local multiplayer, each player controls ONE orb. You'll need to talk, coordinate, and try very hard not to blame each other when things go wrong. The tether transmits every tug — you can literally feel your partner's bad decisions through haptic feedback. Relationships may be tested. We accept no liability. 50+ LEVELS OF "OH, COME ON" Five handcrafted worlds that start friendly and end personal. Star ratings reward speed and efficiency for the overachievers.
