Avoid the spikes

Tap to flip gravity, but only when you're on the floor or ceiling. Time your flip to slip past the spikes.

How to play Avoid the spikes

Tap or press a key to flap upward. Gravity pulls your character back down. Spikes scroll in from the right and you have to slip through the gaps. The longer you survive, the faster the spikes come. Touching a spike ends the run. Your score is how far you made it. There is no end, just one more attempt.

Tips

Tap in short rhythmic taps, do not hold or mash
Stay near the centre, the gaps spawn there most often
Look ahead, react to the next spike not the one in your face
After a death, take a break for ten seconds, reflexes recover fast

About Avoid the spikes

Endless runners blew up after Flappy Bird in 2014 turned a tiny bird and two pipes into a global phenomenon. The format goes back further, helicopter games and SFCave on Palm pilots in the early 2000s. The recipe never changes. One button, no end, leaderboards. Our version trades the bird for a glowing block and the pipes for spikes, and it runs equally well on a phone in landscape and a desktop with the spacebar.
