Under the Red Sky Game

Under the Red Sky is a 3D parkour game built around speed, not exploration. You start each of its 70-plus levels on a narrow platform floating in an empty sky, and the only goal is to reach the end as fast as possible by wall-running, vaulting obstacles and chaining jumps without losing momentum.

The world is stripped down on purpose: white checkered platforms, a few colored markers, and long drops on either side if you misjudge a jump. Levels reward finding your own line through a course as much as executing it cleanly, and a running clock keeps every attempt honest.

Controls

• WASD or arrow keys to move
• Spacebar to jump

Tips

• Momentum carries between jumps, so a clean run-up into a gap clears more distance than jumping from a standstill.
• Some levels hide optional secrets off the main path — worth a detour on a replay once you know the fastest route to the exit.

Best suited to players who enjoy tight, replayable time-trial platforming over a long adventure — short levels you can restart instantly and shave seconds off.
