Running out of energy is the real threat, not falling
This is a physics bike game built on Box2D, so the usual danger in this genre is misjudging a jump or landing wrong. That happens here too, but the game adds a second, quieter failure state: energy. It only moves in one direction - down - and the pickups scattered along the track are the only way to top it back up.
When it runs low the bike does not stop outright, it slows down, which is arguably worse than an instant loss because a slower bike is also a worse jumper. A run that would have cleared a gap comfortably at full energy can come up short once the meter is low, so a fuel shortage tends to compound into a physics failure rather than staying a separate problem.
The practical result is that route-reading matters as much as reflexes. Seeing an energy pickup ahead and adjusting your line to collect it is often worth more than a technically cleaner jump that skips past it.
