Good to have a fellow zachtronic player here! I am glad you enjoy the game!
Yeh it took me quite a while to nail down the core mechanics and that really drains a lot of time. I guess it's around 10 days or so. Would really want to get the tutorial in too but sadly ran out of time. Ah, btw the duplicator currently is a bit bugged, that somehow it only works when input from the right (and the equivalent direction when rotated) came last. Some how this got missed during the final check :(
