Game: flower knight girl from nutaku_net (i'm not allowed to post links, sorry)

I tryed to use cheat engine to get more flower gems, money, but it didn't work, is that encrypted??
the only one work is for stamina at first, but now it didn't work either, i try to reduce stamina time charging, but still not work, can anybody help me on that??? (the value on game has canged, but when i try to use it the game session is expired or an error occured)
