Well, in all honesty I’ve done NOTHING on my game this week. I did recently buy myself an Xbone controller, so I have been messing about adding gamepad controls...
Very nice to see you drawing on paper, which is really how I think sketches of ideas for games should be done, since they were done that way before (and still are in many cases). All the great games of the past era were drafted on paper and many of the animations were drawn, even after being converted to pixel art. I write everything down on paper first, and on the same paper I write down ideas, mechanics and even the logic of programming (when I can). Paper, pen and pencil are my best friends. Your inventory is very interesting already on paper ...
I agree with you on the pen/paper thing - it's great to be able to scribble ideas down, erase things, annotate things and quickly compare sketches side by side as you create stuff.
