OK, I found it. The ridiculously hidden board is on the screen where the side of the steps are in the middle of the screen, and the shelves are on the left. It is the third floorboard from the right wall. After finding this I managed to complete it, but I don't see why I had to make this crazy bit of wood and put screws and things in it. Seems to be some kind of ladder? I'm not really sure.
The normal mode is easy if you win the first round. After that just pick rock scissors paper in that order, and repeat. AI will lose and you don't need to upgrade (you get award for this).
Pointless game.
I would have thought it'd be independent of frame rate, for sanity purposes...
I thought of a feature I want... to protect against browser crashes (dunno why those should make it fail to save... surely it just writes to the disk every 60 seconds?), I reload the page every few hours when I remember to... and I seem to have this amazing skill at reloading on the 56th second or so. So how about a tiny little disk icon flashing up in the corner when you save?
*waves paw at the 14 people above him on the high scores*
Just you wait! Sooner or later your computers are going to crash overnight six or seven times and I'll win! :D
Life bar is very confusing, and the first proper boss came at the same time as a miniboss, and the usual complement of other random enemies, which was basically ridiculous. ;p
I can understand why some people's scores would "jump up" if, like me, they left the game running in one tab and played games in another (thus causing the chat and API to disconnect). Their save file would keep ticking along, but their highscore progress would suddenly catch up. But Dark_Shuyin wtf?
