Probably not? The slow rate of acquiring hammers is meant to slow you down. Since the game makers don't have new contents to release, and haven't in a while... (see this thread complaining about the last of levels past 49, there are tons of others) they need some other method to keep us from mastering everything they have available. So they keep the hammer/shovel rates low to keep us all from finishing everything too quickly.
When folks finish, they complain, get bored, find something else to play. S8 doesn't what that, so here we are!
