My brain started to work in 1 hour after waking up! I have decided to make game about duels in block or square world. I can do only pixel art, so whole game will looks like this swords:

Swords – training, short, long, gold, emerald, ruby, diamond and shadow
It won’t be anything super, hyper, mega, ultra, but I will focus more on gameplay.
Anyway, this is my first time in Ludum Dare!
