It is not exactly a Lego clone.
Parts and instructions make you confuse.
Instruction is not good copied. So one time, you have the Lego built displayed. One Time you have the alternate built for few solutions. And you looking for parts all the time, because you are in between of both Solutions.
For exaexample the black Top of passage from one waggon into the other. The floor with the white special tiles. And the wheels with the black special tiles.
Both 2x12 plates were missing!
This is building Step 3. I looked in all Part Bags at the beginning.
This is also very confusing ans frustrating.
The Part quantity is not right. You don't know, if you missed something or it is extra. Or the story with the alternate building solutions with remaining parts.
The minifigures are not very close. So if you change the parts on minifigures, please change the instructions too.
I'm used to get better quality from joybricks.
But this was the first set with such issues.
