Play Grave Flight • Free

This is the single mechanic worth understanding, and the game never explains it. Falling is not a constant speed - it accelerates. Every frame you spend not flapping adds to the downward force, so a fall that begins gently is moving considerably faster a second later. Then, the moment you flap, that accumulated force is thrown away and the fall starts over from nothing.

The consequence is that flaps are not interchangeable. Two quick flaps and one flap after twice the delay do not leave you in the same place, because the second case spent that whole gap building speed you then have to undo. This is exactly why panic-tapping after a long drop rarely saves anyone - by the time you react, the bird is carrying more speed than a single flap can cancel.

Play it as a rhythm rather than a reaction. Small, regular taps keep the accumulated force near zero and the bird close to level, which makes the whole game feel much more controllable than it first appears.

There is a hard limit above the top of the screen, and crossing it ends your run exactly as a trunk would. No warning, no bounce - the bird simply dies somewhere you cannot see it.

This is a real departure from the game everyone assumes it copies, where flying too high is merely a waste of time. Here it is a way to lose, and it catches out anyone who has learned the habit of climbing into the roof to buy thinking time before a low gap. That escape route does not exist.

Because there is a lot of empty space above the trunks, the danger is easy to forget for long stretches and then arrives all at once during a sequence of high gaps. If you find runs ending for no apparent reason, this is usually why.

The trunks travel at a fixed speed, arrive on a fixed interval, and the gap between them is always the same size. Nothing in the game escalates - a run at step 5 is mechanically identical to a run at step 50. Only the vertical position of each gap changes, and that is chosen at random rather than building toward anything.

That makes it a game of consistency rather than survival. There is no wall of difficulty you eventually hit, so your score is a fairly honest measure of how long you can keep making the same small judgement correctly. It also means a bad run is genuinely just a bad run, not the game outpacing you.

It rewards a very specific mindset: the run does not get harder, but staying interested at step 40 is harder than at step 4, and that is where most attempts actually end.

The collision area is an ellipse tucked inside the bird sprite, noticeably smaller than the drawn character. The wingtips and the tip of the beak overhang it, so a pass that looked like a graze usually was not one.

The scoring trigger is separate from the trunks themselves and slightly narrower than the gap, which is why the step counter ticks up a fraction after you feel you have already cleared it.

None of this is something you can exploit deliberately, but it is worth knowing that the game is being more generous than the artwork suggests. Aim for the middle of the gap and you have more room than you think.

Your best run is stored in the browser and survives closing the tab, so the Higher Step figure on the game over screen is a genuine long-term record rather than a session count. Beat it and a NEW badge appears alongside it.

Everything else resets. There is no run history, no per-attempt breakdown and nothing carried between attempts, which suits a game where a full run takes under a minute. Note that game over returns you to the title screen rather than straight into another attempt, so a fast retry is two presses rather than one.

The M key mutes at any point, including mid-run. On Firefox the soundtrack is deliberately quieter than on other browsers, which is a quirk of the game rather than anything on your end.
