Started at 9pm on Saturday. Drew all art assets for game. Took all day! Literally all of 16 hours minus about 2 hours combined meal times.
Part of what took a long time was the fiddly nature of the controls I was drawing, plus having to fit everything on the screen was hard, and note down all the positions of everything and draw controls in various positions. I was making game design decisions as part of designing the screen. There are some sprites not shown on the picture, which is just the main screen before you have started playing.
