It's amazing what just one button can do. In Trigger Knight by MINTSPHERE, your handy dandy mouse button is all you need to upgrade a cute little knight and buy her more lifespan as she charges relentlessly towards the right side of the screen in this experimental action RPG.
The game is mostly luck, since there's pretty much no skill needed to click on the various upgrades that come by. Your only real intellectual task is deciding whether to buy or not, using the "upcoming" feed at the upper right to hedge your bets. But there's a certain mindless yet addictive joy to watching your heroine wallop a wolf, and the charging soundtrack really pumps up the adrenaline as you bite your nails hoping for a lifespan upgrade to come along before your poor character keels over. A nice proof-of-concept that's fun for a coffee break and hopefully a precursor to a more fleshed-out version later.
