Thank you very much for the feedback! Sorry for the problems during your gameplay :/. I really have to fix a lot of things in it, it’s still a very bad game and have a lot of design problems that needs improvement.
Regarding the box, you get an upgrade in another area that allows you to drag it. So, the text saying "It's so heavy", but from what I saw it was not clear to the players. Sorry about that too, I hope you can have a little fun and sorry for my bad english too.
