Tatamigaeshi

Description
Tatamigaeshi is a league 4 trap that confuses and hurts any player who enters horizontally. It hurts any player who walks into it, dealing extra damage the higher agility they have.

Strategy
It can be put next to a set of electric rails, which will block anybody from entering the room vertically (most of the time). It can also be used to confuse a lot of players, so that they will accidentally walk into a powerful trap.

To avoid it, just try to enter its room from above or below. If you get confused by it, it's sometimes okay to make a wrong move, but if you moved horizontally, DO NOT go back into the room, unless you're about to escape. If making the wrong move could arrest your Cat or lose too much willpower, you should either wait for the confusion to go away, or heal it.

Trivia

 * If you ran into a Tatamigaeshi while confused, the game would softlock, resulting in your willpower slowly draining making victory impossible. This bug was patched in version 1.5.6.
