Color Tunnel Game

Color Tunnel drops you inside a glowing, geometric tube and doesn't let up. A rolling ball carries you forward automatically, and your only job is steering it left or right fast enough to slip past whatever the tunnel throws at you next. There's no map to explore and no story to follow — just a straight line forward, walls closing in, and a run that ends the instant you clip something.

What makes it click is the pacing. Early on the tunnel is mostly open space with the odd wall to dodge, so you get a few seconds to read the shapes ahead. As you survive longer the speed climbs, obstacles start stacking closer together, and spinning barriers and swinging pendulums start mixing in with the plain walls. It's a short, replayable loop: die, restart, try to beat how far you got last time.

Controls

• Desktop: Left and right arrow keys, or A and D, to steer the ball side to side.
• Touch: Tap or swipe left and right on the side of the screen you want to move toward.

Tips

• Look a few obstacles ahead rather than at the one right in front of you — the tunnel's colors make near obstacles easy to spot late.
• Small, repeated taps steer more precisely than one long hold, especially through narrow gaps.
• Spinning barriers and swinging pendulums move on their own timing, not yours — watch a full rotation or swing before committing to a lane.
• When the speed ramps up, favor whichever side has open space over whichever side "feels right" — reaction beats habit here.

It's a quick-session game built for a few minutes at a time: pick it up, chase a longer run than your last one, and put it down.
