Twang is entirely mouse-driven, simply grab the smiling nodes and pull back in any direction. The angle and intensity of your tug makes all the difference, so if you want to go high pull straight down, but if you want to move forward, give the node a little nudge in the opposite direction. With practice you can get the subtle nuanced flinging to send you almost anywhere you desire.
Analysis: While Twang shows the same level of polish and style as other Nitrome games, I can't help but feel it comes off as a little random. Blind luck is always a part of gaming, but in Twang every toss rolls the dice and gives you very little control over the outcome. It's the same sort of feeling I get when playing pinball. Practice, as always, curbs the randomness, but it's still a little too uncontrollable for my taste.
One of the best things about Nitrome games is the variety of new obstacles and creatures that appear as you progress through the levels. Twang is no different, introducing a number of fun twists just when you start to get used to everything.
Worth its weight in rubber bands (maybe twice over!), Twang is a fun and wacky game of platforming physics. And you just gotta love that twanging sound.
You can also play Twang at the MTV Arcade.
