Haha yeah!
I remember I was so excited with the ability to fly. Fight monster while flying etc.
Then I got so disappointed with the execution, it was slow, and there was a cash shop for those flying swords and other stuffs (I don’t remember if it was possible to upgrade without $).
If I recall correctly the game should create a file in root game directory with “mdmp” extension.
You should try to verify game files from steam in case there is anything it I’ll try to download again the files in error.
