Yuckfu is limited, to say the least -- Its only two modes are a tutorial and the actual "game." While the tutorial is a useful way to begin, it showcases the most frustrating parts of the game right off the bat. First, a little robot introduces itself and presents the main objective: simply hover within a designated circle for 3 seconds. Three seconds never felt so long. In order to fly the Bo382 robot, you must tilt your iDevice accordingly. Problem is, the bot is overly sensitive to the tiniest movement of your iDevice, sending it clear across the screen at the slightest nudge. Putting the iDevice down further highlights the accelerometer calibration issues -- Bo382 will fly upwards at an alarming rate. With no obvious neutral point, hovering nearly is impossible. While it is possible to get used to the controls as you go along, they never fail to be harrowing and frustrating.
