The construction mode needs to be expanded a lot. It needs more space to build in, ability to make ur own puzzles (with the goal zones and stuff) and share them online, and it needs some more items(like Mel and his house). And it also needs the ability to have more pieces on the screen at once. I dont know if anyone else has this problem, but if I put too many pieces on the screen, it will automatically start taking other pieces out. It is very annoying.
I know this would be a huge update but I would be willing to pay more for it.
