Whenever anyone asks... ...my answer is always Monospace! Just a super awesome puzzle game. Though nothing like Portal in terms of gameplay is just always gives me that same feeling of progression and satisfaction.
shift is the best app store game ever. (theres also a lite version you can try) nanosaur 2 is also amazing which i definitly reccomend and omg i cant believe you dont have payback! dont listen to all the bad reviews it gets its actually incredibly fun and controls good as well. a much better game than the terrible (imo) car jack streets but for the ones you listed lightbike is really good. also though lightriders is great as well which is very much like lightbike in addition to multiple viewpoints
Bounce on and Tori Toki are by far my favorite iphone games. I love Bounce On and think it's does not get the respect it deserves.
