LD39: Depths of Mars

The year is 21XX. The energy crysis on Earth causes some discomfort. As the solution, bot model LD39 was sent to Mars to recover energy crystal from its depths. Control the bot, but be careful: bot has limited capacity of energy! It can stop functioning at any time (spoiler alert: it will probably function all the time you need). Controls: Left/Right to move Z to activate jetpack.
