I've tried, but there are a few factors preventing me from making Android ports:
1. I don't have an Android for playtesting (though there IS Bluestacks, but I guess I don't know how that compares to playing on your phone)
2. Past attempts to convert my games into APKs haven't gone well
3. Probably the biggest factor: a number of plugins used in my games are incompatible with Android. In order for me to make a game that can be ported to Android, I'd have to be designing it that way from the ground up.
My games do have browser versions on Newgrounds! (GOCKHAUS will get uploaded there too before long)
