The tutorial could definitely have some work done on it. Some stuff is badly explained; explained decently, but there is enough other stuff around it that people just gloss over it; or just not explained at all.
I feel like it does expect the player to check the Hints menu, which is somewhat valid, cause it actually has a ton of useful info when you read through it. Only issue is, it doesn't tell you to, and nobody actually checks the Hints menu when they need help.
0.8.2b added an Item Box to the storage room above the garage, with a little note telling you how to use it. Selling the trash should probably be at least hinted at, rather than directly telling the player to do so. It does have more uses than just selling it, and directly telling the player to sell the trash will probably just make them not explore any of its other uses, like turning it into useful crafting materials that actually sell for more than the bagged trash.
