Túnel

Arrow keys, WASD, swipe, or the pad. Left and right move you between three lanes. Up jumps, down slides, and each lasts long enough to clear one thing and no longer. The colour tells you what to do: amber sits on the floor and wants a jump, blue hangs from the roof and wants a slide, red is solid and wants a different lane. Purple orbs are worth points and always sit in a lane you can survive, so following them is the safe read. The corridor speeds up with distance. Nothing ever blocks all three lanes at once, so every crash was avoidable, which is the annoying part.
