I completed the whole game, i want to replay it but now i stumble on a bug, In the Strange Garden at the end there's a white door, alice is to small to enter so i need to find the Oepelkoekencake, if you get it you get a little movie, but after it Alice still was small, the door still isn't opened and the Oepelkoekencake is gone, also Alice keeps saying she's to Big/Tall to enter, but she has the size of Mallymkun
