I think that with adobe losing support and ground over to html5 (and other technologies), it would be wise for the developers to start looking into other alternatives for their future releases.
The advantages of flash/air were that they suppose to be web and cross platform friendly, but the future is starting to look more and more uncertain for these.
So like others have mentioned some possible alternatives would be:
-Html5
-Java
-Google's Native client / web store, (can be used for your current games now if wished) examples:

or combination of the above.
so yes, more and more alternatives are starting to appear.
anyway thanks for making real nice, cute and inspiring games.
