I made version of Godot game engine for OUYA as current official version does not work. It is however based on old 2.1.6 version of the engine. Official editor may or may not work (I haven't tested it...) with these custom export templates.

What about 3.2 with OpenGL ES 2.0 renderer?

Hi, very good idea. I was trying to get the newer 3.1+x versions to work but despite offering GLES2 support they rely on the availability of GLES3 driver (libGLESv3.so). Out of the box the 2.14 works with OUYA, but the controllers joysticks do not work (buttons and joypad are mostly functional). After 2.14 minimum Android SDK was raised to 18 but OUYA is 16, and still requires signing with SHA-1 instead of SHA-256.  (So probably the export templates will not work with newer 3.1+ builds without  the changes you made to the export.cpp)
Edit: the left Joystick does work when reading the axes directly in 2.1.4 but throws errors in ADB Logcat.

Any chance you guys can post this over at Ouya.World forums so that others can use it?  Also at the discord?  That link should be on the main page
