Danger Jump

Keep jumping forward as far as you can and avoid falling.
Just tap on the left side of the screen to make a small jump and the right side to make a long jump. Evade the rising sea-level, collect gems and unlock more props.
Try not to fall into the sea and be careful spike, trap etc. How far can you go?
The sea-level's rising speed is too slow? Wait for a few seconds and jump while the water comes closer…
