About Rolling Knight
A real slope, not a set of rectangles
The ground is a continuous height field sampled per column rather than a list of platforms, which means slopes are genuinely slopes and the ball's contact angle is computed from the actual surface under it.
Leaning forward on a downslope adds to what gravity is already doing; leaning back on an upslope bleeds speed off. Neither is a substitute for the hill - the lean is a modifier, worth about a quarter of what the terrain contributes.
The terrain is generated with deliberate features rather than pure noise. Every few hundred pixels it commits to a crest or a dip, which is what produces the launches. A run down a noisy hill is a wobble; a run down a shaped one is a series of jumps.
Landing is the skill
Coming down with the ball's spin roughly matching the surface keeps your speed. Landing badly scrubs nearly half of it off, which in a game with a clock is expensive.
While airborne, the left and right keys control spin rather than direction - there is no steering in the air. So the whole of a jump is a small preparation for the landing, and the landing angle is drawn as a guide line at the point where the ball will touch down.
The target is not simply 'straight'. Landing on a downslope wants a little more spin than flat ground, landing into a rise wants a little less, and the guide line shows the angle of the surface you are about to meet.
Checkpoints and the clock
There is no death from speed. The only way to lose is to run out of time, and the only source of time is checkpoints, which are 900 world units apart and each add twelve seconds.
That makes going fast always correct - a rarer property in an arcade game than it sounds. Most games with a clock have hazards that punish speed; this one has none at all, so every decision is simply about carrying momentum.
The distance to the next checkpoint is shown at the top of the screen and turns green when it is close, which is the number that matters when the clock is low.
Airtime, flips and the score
A launch of more than half a second pays: 45 points a second of air, 90 per full rotation completed in the air, and up to 55 for the landing quality. Short hops over bumps pay nothing, which stops the score becoming a measure of how bumpy the hill was.
Rotations are counted from the spin at the moment of takeoff, not from the rolling the ball was already doing, so the flip count means what it says.
Treasure sits along the ground and in arcs over the crests. The arcs are on the line a big launch actually takes, so committing to a jump and collecting are the same action.
How to play
- Press Space, Enter or tap to start rolling.
- Press Left/Right or A/D to lean. On a slope this adds to or bleeds off your speed.
- Press Up or Space for a small hop - useful for leaving a crest a fraction earlier.
- In the air, left and right control spin. There is no steering.
- Match your spin to the slope shown by the gold guide line to keep your speed on landing.
- Reach checkpoints for twelve seconds each. They are the only source of time.

Scoring
These are the point values this game awards, before the combo multiplier is applied where it uses one. Hit quality changes the figure: a strike at the centre of the correct moment is worth substantially more than one at the edge of it.
Tips
- Lean into downslopes and let the crests throw you. The hill is the engine.
- Watch the gold guide line - it shows the angle of the ground you are about to land on.
- Landing badly costs nearly half your speed, which in a timed game is worse than a hazard.
- Small hops over bumps pay nothing. Save the score chasing for real launches.
- The checkpoint distance is the number that matters when the clock is under ten seconds.
- Arcs of treasure over a crest sit on the line a big launch takes. Follow them.
Common mistakes
- Trying to steer in the air, which does nothing - the air controls are spin only.
- Braking into every crest, which trades the launch for a safety you do not need.
- Spinning for flips at the cost of landing angle. Landing quality is worth more per jump.
- Ignoring the clock because nothing can kill you, and then finding the checkpoint is 400m away.
- Tapping the lean keys rather than holding them, which barely affects a rolling body.
Features
- A continuous terrain height field with real slope physics, not a set of platforms.
- Landings graded on how well spin matched the surface, with the angle drawn as a guide.
- Airtime and rotation scoring measured from the moment of takeoff.
- Deliberate crests and dips generated into the hill, so launches are shaped rather than random.
- No hazards at all - the only way to lose is the clock.
- Personal best distance, score and airtime stored locally.
