In this short ectocomop game, you are trying to enter a tomb and lay a spirit to rest. However, the spirit copies everything you do, performing your actions two turns later.
This causes a lot of trouble, as the puzzles include latches that you can push open and push close, so he pushes stuff closed as you push it open.
I had fun with this. However, out of the three puzzles, I twice thought I had the right solution and failed; both times, it was because I didn't realize that the ghost goes first in simultaneous actions.
There are just 3 puzzles. Fun for puzzle fans.
