Race Rider v0.1.49
Touch right for minimum gas. Slide up from that spot for more; down for less. Lift to coast. The same tilt and suspension are used. These settings restart the ride and have separate local records.
Speed percentages use 8 on the speed display as the reference. They are powered flat-ground targets; descents can go faster. Start from rest still requires acceleration.
25% means a quarter of the visible game height. The travel distance is fixed when your thumb touches down.
Rear tire: green → yellow → orange near the grip limit; red = slipping; pulsing red = recovering; dim gray = airborne. Best grip is at the orange/red boundary.
Fast gas movement temporarily reduces grip. Start with about 1.2 seconds to slide from minimum to full gas. A higher value makes quick gas less forgiving; 0 switches this effect off. Your thumb controls gas immediately; the game does not smooth or optimize it.
Demand above the grip limit spins the rear wheel. Ease off below 90% of the grip limit to recover; coasting or braking on the track also restores grip. Full gas can recover as road speed catches up. Engine pull and grip use game acceleration units. Steady gas restores the normal grip limit. Climbs use exactly the same drive and grip rules, with no extra uphill assistance. Internet checks and shared times stay in Standard mode for this experiment.
Keyboard: ↑ / Space full gas; Shift + ↑ / Space minimum gas.
Gas and brake respond immediately. The outside-clock check connects in the background; a slow connection can make the check unavailable. Local results still save.
Keep a file with your saved maps, editor draft, best runs and replays, settings and rider profile. Works offline. Each backup gets a date and time in its filename.
Keep your backup private: it includes your rider recovery code. Friends results and attempts stay with the online service.
Start with reference sensitivity. Changing bike restarts the track. Internet timing is a basic check, not full anti-cheat verification.
