For me it was unplayable due to different errors and crashes, couldn't get past 5 minutes of playtime.
One of the erros was when trying to create the very first world:
"ERROR in
action number 6
of Step Event
for object Control:
File is not opened for reading.".
I tried ignoring it, the game crashed.
2nd try: Got to create a world succesfully, but when trying to access any of the guides, the game crashes and I have to reload.
