Yes, I can! You Can't Possibly Expect Me To Do That (or YCPEMTDT for kinda-short) is a platform puzzle game that's all about dying, healing, mid-air double jumping, and probably dying again. To reach the star in each stage, you have to smash into spikes and other obstacles to kill yourself. While "dead", you fly through walls, allowing you to maneuver to impossible areas and collect health packs which bring you back to life. Some of these stages are absolutely crazy, and you'll have a great time figuring out what to do.
A brilliantly-executed platform puzzle game by Jesse Venbrux, creator of the Karoshi series
of games. In Focus, you take control of a little guy trapped in a cave stuffed with traps, missile-firing robots, and lots of other baddies. Early on you learn how to use "focus mode", an ability that lets you teleport yourself anywhere the blue circle extends. Momentum is applied when you teleport, allowing you to move yourself to surprisingly exclusive parts of the screen. This mechanic is superbly implemented and the puzzles require you to think of new ways to use it in almost all of the 50 levels. As Venbrux put it himself, "very solid, difficult-but-let's-try-one-more-time gameplay".
