Anyone interested in playing old Amiga games would likely be technical enough to install uae. If they aren't technical, Cloanto's Amiga forever install very easy and is relatively cheap.
For a specific phone version it takes a tiny bit of technical background, but who honestly wants or needs old desktop games on a phone? Besides, there is at least one open source project to do exactly what WRIT is proposing that will be free and released very soon.
WRIT has nothing but cold air. They never had hot air, only lukewarm air once upon a time. I can rattle off all of the major "amiga" sites with links and you would be amazed just how negative the reaction is. That $143 donated to Kickstarter? I doubt a single penny is from an actual interested user. It is probably starter seed money from bogus users by people connected to WRIT trying to show some interest to lure others in, but it isn't working.
The "amiga" name has been sullied so thoroughly and completely for so many years, there is no value left in the brand. I don't know how much involvement McBill has left in WRIT these days, but he pretty much single handedly killed any chance for the brand name more than a decade ago. Coleco, Odyssey and even Tandy brand names hold more value these days than "Amiga". When people hear the name "Amiga" in 2015 they think failure and/or scam.
