The Power of Love
In Denis Vasilev's cute but very grindy action game The Power of Love, a knight and a princess are smitten with one another, but the king isn't having any of it. So what's a lovestruck knight to do? Why, beat down the castle, using the coins the king hurls in distaste to buy new upgrades to further increase your punching prowess. Just click and hold to swing your weapon (initially just the very lute you used to serenade your lady love), and move the cursor to move the knight, walking over coins to pick them up. Move alllllll the way to the left to enter the shop and purchase speed and power improvements. Cute and simple? Sure. Fast? Not so much, as initially the knight moves so painfully slowly you'd be forgiven for getting frustrated before your first speed upgrades. Your goal is to eventually destroy the castle, thus freeing the princess to love as she wishes, though one could argue maybe the princess should get off her frilly butt and do something herself if she were really in love. Still, while it could definitely have been streamlined, once you start unlocking new equipment and thus the king starts hurling more types of treasure, things get a lot faster.
