I have had it three times in a row, and I cannot summon more than one. I think it is preventing the aquisition of more summons.

The game launches with a tiny window. Is it supposed to do this?

One is where there are two rotating circular platforms where they spin you around, and I thought you were trying to get the two blue lights lit up with the blue energy orbs... the other is a room close to it, where there's a teleporter behind an iron fence... I thought the goal with this was to get the blue lights to light up at the same time with the same blue energy orbs... but no matter how accurately I feel I'm doing it, it's not opening up the iron fence for me... so unless someone can tell me what's ...

When confronting an enemy group that has Caterpillars the messages that state which monsters appear say "Appeared Succubus" instead of Caterpillar. I recently got the "collected all summons in the game" Achievement and no Succubus. Bug?
