The videos were intended to BE the tutorial and show you - rather than tell you - how stuff works. Sadly, they were far too large to meet the upload criteria and cuts had to be made. As far as your question about banking materials - yep, you are correct there is currently no penalty to just banking right away. It's something we thought about and were planning to add enemy damage to knock items off, but couldn't get it working in time. So consequently, the shields also are just cosmetic. But glad you otherwise enjoyed the game.
