    Kids Games: We Sow Light

    Kids Games in Flash

    Using something I've made? http://www.arrall.com Please, consider contributing in some way to any app I'm working on. Free kids games in a coding language you can freely acquire and create with. The version at http://www.wesowlight.com/ partially works. Tested to run on android 4.0.3 and 4.1 (after googling and installing flash player) You have to twist, poke, and guess your way into full screen mode, but it does seem to work. If it appears to consume your entire screen, touch the bottom black bar to un-hide the nav buttons. Currently working on the first game theme: Splat. Splat: Tap the main splat button or a sub-game. Match colors, shapes, both, or just go free for all.
