Great little game, which also works on MO6 as well as the MO5.
One thing however. I've tested the game on both a real MO5 and MO6 and the joystick controls do not work. What I mean is the joystick is not detected. It's a pity because I much prefer using a joystick when playing in real hardware as they are a lot easier to replace than a keyboard membrane.
Note: I haven't tried the game on an emulator so I cannot say if you can use a joystick there
