Varuna is a prototype retro shooter . Download it for free here : http://forzapedro.itch.io/varuna
If your pad is not working properly with the game, please try installing the joytokey : http://joytokey.net/en/download
The setting is available in the option menu.
You can pause the game using your pad, but to disable it, you'll have to press any key of your keyboard (Ok it's totally stupid but it's a bug).
