Thanks for checking out my game!
The rate at which items can be picked up does seem to be a common criticism, so I'm adding that to the list of things to work on. Currently, I just have a modifier (based on your Dexterity) that affects the base time to pick something up (based on the object's weight).
Thanks for pointing out the issues with crafting. I'm looking through the code on that, right now. =)
I appreciate the feedback! Every comment and critique helps.
