Tap to fly. Don't touch the walls. It only gets worse.
Hell Copter is a one-button flyer in the Flappy Bird / classic 'Helicopter Game' mould: tap (or click, or Space) to lift, let gravity pull you back down, and thread the gaps between the pipes. Proudly stupid and minimal — but now the pipes glow red-hot, embers drift up from below, the screen reddens as you speed up, and crashing goes out in a shower of fire. (Currently v0.75 — Beta.)
No story, no goal beyond the next gap. The purest possible arcade loop — the only thing between you and a higher score is your own thumb rhythm, and the walls are getting hotter.
Every tap kicks the copter upward; stop tapping and gravity takes over. Fly in a steady rhythm — over-flap and you smack the ceiling, under-flap and you sink into the floor. The copter tilts with its speed so you can read a climb from a drop at a glance.
Pipes scroll in from the right with a gap in the middle, their edges glowing red-hot. Fly through to score. Every 5 pipes the scroll speed ticks up — and as it does, the background reddens and a danger vignette creeps in from the edges. There's no top end.
Clip a pipe or hit the floor and the copter bursts into a shower of embers with a screen-shake and a crunchy retro crash. Your score is submitted to the leaderboard, and it's one tap to dive back in.
The run does not just get faster, it gets hotter. Embers thicken and a haze creeps along the floor the further you fly, all of it capped so the pipes stay readable and a weak machine keeps its frame rate -- the inferno reaches full strength around 220 and stops there. Nothing moves except you until 100. From there the pipes begin to breathe, and the drift builds until 450 -- where it STOPS. Past that the only thing still rising is speed, so a long run never turns into a coin flip. Every 50 the molten caps on the pipe ends shift shade, cycling through a narrow red-to-amber band. It is a quiet way to feel how deep you are without looking at the number.
Crash three times in a row without passing a single pipe and the helicopter is permanently burnt: red-brown body, soot marks, a cooked rotor and a trail of smoke behind it. It never washes off. Passing even one pipe resets the streak, so you have to fail three times cleanly to earn it.
