William the Conqueror
Neither rain nor snow nor really enormous vampire bat will keep William the Conqueror from rescuing the princess in this simple incremental game that plays a bit more like an "endless runner" arcade game, only with lots and lots of stabbing. And upgrades! William will move and automatically attack enemies as he walks, and all you have to do is spend the cash he earns from his slaying on upgrading his skills and abilities. Chances are he's going to need some help, however, so you'll also have to click on the screen to increase his damage, or on his fireball and freeze spells to use them. Make sure to check the Achievements tab to claim your rewards when you reach various milestones! If William is slain, well, it's right back to the beginning to keep on ploddin', but things will move much faster once you've upgraded several skills a few times. While William the Conqueror plays by itself, it does so very slowly, and the need to manually respawn means you can't just let the game run to rack up coin unattended, though the expense of upgrades tends to be balanced by increasingly higher bonuses. Coupled with its relatively simple, grind-y nature, that means it won't necessarily be for everyone, but once it gets rolling, the enemies, upgrades, and bright cartoon style makes this a solid little diversion to let you save the kingdom without lifting a finger. ... well, just the one, I guess.
