Thanks for your feedback! I'm happy to hear that you would buy my game if it was more polished and multiplayer :D
About your "pain points" I totally agree. The lag can be fixed, items from the box are sometimes too bouncy and that you can take items from the tutorial is just lol.
The tutorial was made in 5 minutes so I didn't think that items can be taken with you, I forgot about that.
I'll try to change those things in the next update (if I even plan to do it...)
Thanks for playing my game!
