(Old)(it's must be cool to use this software for pixel art game, i would like to use it for that, but this is not possible) ( (Update : They are Pixel art mode and it's work very good)
Why is not possible?
The exported map should be fine for pixel art.. and you have a pixelated checkbox to enable pixel preview.. are they not working? Could you share one of the pixel art sprites that are not working for you? Yo can also open an issue on github!
your games look great by the way!
