Page "Tetris Plus" Paragraph 3

The player's goal is to guide this archaeologist to the bottom as fast as possible.

Two blocks wide and tall, he will aimlessly walk forward until he bumps into a block, after which he turns around and walks the other way.

If he comes across a gap that is large enough for him to fit through, he will fall down onto the blocks below him.

Conversely, if blocks are placed on top of him, he will climb up them until he reaches the top.

As one could guess, if these blocks lead too closely to the spikes, the professor will die.
