I converted a game I made a long time ago when I first got TGF2 to work with the Android exporter. The objective is to catch green circles and avoid hitting red ones.
I haven't tried it on the emulator (as an Android developer prior to using the MMF2 Android exporter, I know how bad it is) but it works on my phone running Gingerbread clocked at 1 Ghz and on my tablet running Honeycomb with a Tegra 2 processor.
I only really have two problems. First is that the menu screen is really laggy. Second is that the status bar doesn't always disappear (but I think that's a known issue)
The APK is here if you want to try it.
