Upgrades, accounts, saving upgrades.

I played wanderers beta a few times.  I had alot of fun in the start but soon i got to max upgrades and well, there was not much to do after that.  Because i got the more food from bunny upgrade and the ""saw"  upgrade i was much weaker then any other player.  I think there should be more upgrades for more content.  I think some of the upgrades should be saved on accounts which you can buy with gold like wilds.  I think this will add alot more content to the game and make it more fun.
