Line tool and fill tool should be pretty easy Once you have a fill tool you should be able to add a "perimeter tool" that would let you automatically draw around what it would fill. This would save a ton of time

It's not really clear how you can make a different size

There is no undo in this app.. :( hard to draw complex sprites

Hi can you please make a new button.. Not sure if there is one but im forced to close the thing and start anew to get a new thing started
