Newer versions are highly recommended:
In this game the android Hachiko flies around in a jetpack and shoots things. It is a little bit an adventure and danmaku game.
If you played the space jam demo the levels are pretty much the same except a few geo changes and a new tutorial level. Graphics were mostly replaced and resolution and pixel density issues are much better now.
The default resolution is 400x300, but you can resize the window freely without worry of mixels. UPDATE: if you play in fullscreen please select your native resolution! Keybinding support is only unity default, so the tutorial only says the defaults. Mac and Linux versions untested.
