Hi, I have a FREE alpha version of my game [tesseract] on the app store. It would be awesome if you could give it a try and offer some feedback. http://itunes.apple.com/app/id503003003 And this will become paid at some time in the future so if you download it now you won't have to pay for it when I start charging!! [tesseract] is a first person puzzle creator for iPad. You can build and share (sharing coming in the next update) levels. This is a screen shot of the kind of level you can create with it. Check out tesseractgame.com for more info. Thanks for looking and double thanks if you give my game a try. Cheers!!!!
