Are your other flash games dead now?
Late response, but sort of yes, but sort of no. Some sites like Newgrounds were working to incorporate Flash emulators and that might be a feasible way to play them by now, and there's also a standalone app called Flashpoint which bundles an emulator with a large collection of old games - I know at least a few of mine are included in there and they seemed to run the same as how I remembered them.
