Hi,
After testing with the deom on Steam, I decided to buy this soon. before using Bitty, I'm learning Defold for a while, Bitty is very light and fun, but I really hope it support xinput, I can't find info on lib like this, although 4 dir+AB should be enough for simple games.
Just 2 cents, but I know xinput breaks compatibility on platforms or just too much button for a 2D game.
