Agree with Zappan, this is a great concept that will surely make a nice game. Some more suggestions: it's kinda frustrating when you dont have a "quit game" button somewhere, and I took sometime to guess that ESC did that. It's quite obvious, I agree, but some HUD elements would get the player more confortable. The physics simulation should be paused during design mode. Check Bad Piggies from Rovio, it has a nice design/play concept and might give you some nice ideas. Last thing: make the controllable muscles colored, this may give some nice visuals and get things more clear to the player.

Again, awesome concept. Thus.. With great concepts, comes great requirements :
I reduce my previous rating to 3/5 until we get : a saving feature, scores (mostly based on levels timing resolution), replay / sharing levels own solutions (such as Fantastic Contraption).
And it would be great to have a scrolling sandbox mode, the screen is way too small to have fun with creatures conceptions. Zooming in and out would be also awesome.
And I was about to forget : applying numbers to muscles shouldn't move the whole structure, it's a bit frustrating. Also, resetting a level should restore the creature to its initial structure.
Finally, those are not complaints, but eagerly expected upgrades to turn this into one of the most awesome HTML5 actual games :)
Thanks for the suggestions. Yes, I wanted to add highscores, since that would make playing the levels much more interesting. Since I did this for the Ludum Dare competition, I only had 48h and didn't have to for something server-side nor the Kongregate-API.
Also, you -can- share your creatures with others. When you are in Design-mode, you can press esc and see the options 'Share creature' and 'Load creature'. That way you can copy-paste the code of your creature to someone else.

I whish QWOP was this easy to handle. Very interesting game and concept, nice use of the mouse buttons thanks to HTML5, that fits ergonomically to the "organisms" conception.
5/5 so far, I've not yet finished the game, yet, this is highly innovative.
