Long runs in Eggy Car come from smooth driving rather than fast driving. Here is how to keep that egg balanced through increasingly difficult terrain.
Maintain steady speed on flat sections. The egg is most stable when the car moves at a consistent pace without sudden acceleration or braking. Use flat terrain in Eggy Car to build comfortable momentum before the next hill.
Approach uphill sections with moderate speed. Too slow and you stall on the incline, causing the egg to slide backward. Too fast and you launch off the crest, sending the egg airborne. Medium speed in Eggy Car lets you climb smoothly and crest hills without losing the egg.
Ease off the accelerator before downhill sections. Gravity will pull you forward, and adding engine power on top of gravitational acceleration creates dangerous speed. Coasting or lightly braking on downslopes in Eggy Car keeps the egg from bouncing off the front of the car.
When airborne, release all inputs. The egg is most vulnerable during jumps, and any acceleration or braking while airborne in Eggy Car changes the car's angle, which shifts the egg. A neutral car lands flatter and gives the egg the best chance of staying put.
Learn from each crash. Note what terrain feature caused the egg to fall and what speed you were traveling. Eggy Car is a game of incremental learning, and each failed run teaches you something about the physics that makes the next attempt slightly better.
