I just, would change Score into Money and buy upgrades, it would increasing the replay value as right now you can do Over 100k in Endless in a quick game, but after that, it's not that worth to play again. 4/5!
Tasselfoot - Root is a nice travel to do for getting cash at the start.
Also, join a guild and quit it, you get 100 G and XP. However , you can't join back the guild.
