Canabalt creator Adam Saltsman and Solipskier co-creator Greg Wohlwend have teamed up to release their latest iOS offering Hundreds to the App Store today.
The premise behind Hundreds is that you must touch circles to make them grow a certain numerical amount. Release your finger and they'll stop growing. The idea is to tap various circles until you've grown them to a cumulative total of 100, but if they come into contact with another object while they're expanding it's game over.
It starts out easy, but becomes very challenging very quickly as the screen gets cluttered and opportunities to enlarge circles becomes increasingly rare. See it in action in the trailer below or try out Wohlwend's browser-based prototype version on Newgrounds.
Right now Hundreds is now on sale for £1.99 / $2.99, but it will climb up to £2.99 / $4.99 on 10th January, so best grab it now if you're interested.
