This is great! Starting another game, it seems that I have to hit ESC which takes me out of fullscreen. I wish that hitting "S" would start a new game. I don't want to take my hands off the keyboard and put it on the mouse.
Things get pretty manic in a hurry! Sometimes the crane chain feels like it could be a bit long, maybe if you could also extend/retract the chain a little bit with a and z.
