I agree with "amateurhour",..
Personally 1 don't need iOS or android exports (could be intresting,but,..), just having a web export (html5(?)) would be awesome, and should be able to run on most devices and OS's.
Doing this in Flash would (if i`m not mistaking) greatly limit the number of devices the games could run on.
one of the things that seem problematic to me would be save-files
