Top of the Indie-gaming industry.
Gameplay:
You'll play a ball of gum called Gumboy, with powerups that are spreaded into the field you'll be able to turn into stuff like a block that can dive underwater, what you're Gumboy can't do on its own, turn itself into a star and fly in the sky to grab more silverdust, and grab a Hickup powerup, to make you're gumboy hickup to jump slightly.
Graphics:
Their very stylish, the silverdust looks pretty neat, and the cartoony WoW-ish characters in it makes it worth a try for silly-graphic whores.
Sound:
The sound is amazingly good, wether its the sound of you rolling on diffrent stuff, or you jumping or you rolling faster then the speed of light, everything sounds good.
Story:
You're a gumboy, theres no story, its about getting from A to B, I told you it was a Indie-game.
You're a gumboy, you can be enhanced with the Magnetiser, which is infinite powerup, with the Magnetiser you can use it to let silverdust flow away from you, the challenge of the game is to move slowly to let the silverdust flow into the end of the game, when the silverdust is collection a portal appears, you jump in the portal and you're in the next level, each level has a certain difficulity, which mainly is trying to figure out how to get silverdust to the other side, or how to reach to higher places without you're upgrades.
If you have some money over, spend it into this, buy it off steam or something, it isn't expensive and it'll let you play it for a good hour or six.
