I'd like to congratulate you for the game gorgeous retro design. I can't help reminding me years I played titles like Battle City (1985) and Return Fire (1995) with my brothers. I also would like to ask if you intend to translate the game into other languages. If so, I could work on its Brazilian Portuguese localization.
Anyway, best wishes for the game development and have a nice day,
