Cube Runner

🎯 How to play

You run forward non-stop and the screen scrolls on its own. Every tap (click / touch / Space) drops a cube under you and lifts you up. When a pit appears in the ground, one cube falls in, fills it, and you cross safely. If you have no cubes when a pit arrives, you fall in and lose a heart. The trick: you can never remove cubes, only add them, and every pit "eats" one of your cubes and lowers you back down - so do not stack too high, because a flying bird will hit you if your stack is too tall (3 cubes or more). Along the way, grab gold coins (1) and gems (5), and reach the finish line 🏁 with as many hearts as you can keep. You have 3 hearts - do not lose them all!
