Thanks for trying out my entry :)
The crane hanging over a spot before dropping a crate used to be a bug XD But it added a slight challenge so I added a timer to "force drop" the crate, so it became a feature.
As for the shop, I should've spent more time into it to balance it out more but with the x2 & x5 earnings options it felt okay-ish IMHO, I've noted it for the future.
