I'm still getting used to mine (the one coldbrightsunlight failed to kill) and I haven't done much with the secret side of things, but mostly I've been enjoying playing with it with the action at 9 o'clock, the feedback right up so that it gets really wild and playing with the poles for variety and switching between the four modes too.
My latest Sonic Koalas nonsense is mostly a Moomindrone T into Grazer and then Ghost Fax. Work's been really busy so I haven't had time to get everything else involved yet.
