the play button doesn't work...

I have the same problem... But I think I know the solution. Try using another web browser. Chrome doesn't seem to like unity...

If you're having trouble with the play button in chrome please either use another browser or allow the plugin but reload the page, that seems to do the trick

The game is Amazing and worth to switch Browser ;).
Chrome in general have trouble with unity so i use firefox.

I can't seem to play it.

Play button worked for me after the browser was in the background once.

I like the mission-style but got stuck on the "science experiment" level. This RPM thing is fun :)

Nice one, although some more explanation at the beginning would help. (I'm a moron, didn't know what I'm supposed to do for a while ;))

Quite fun and more challenging than seems at first. Could use some visual effect when colliding / loosing population.

Nice physics!

Tricky to play... physics nice. Managed to 'dock' with Sun for first mission but failed second - quite harsh you can't retry just moves you on ;( Original and fun.

It's the three legged race of planets! Cool little idea, good physics. Hard but you only blame yourself.

Very neat and original idea, IMO. It was well executed. Even if the graphics were very minimal, the gameplay was fun.

Great take on the theme and neat physics. I personally found it very challenging to get the worlds to spin. Good job!

Very cool idea! The humour was a nice touch. And it worked very good as multiplayer, I played it with my partner. My hand still hurts from the first 40 RPM-mission. :)

Neat idea, well executed - fun to play with a friend! Nice!

Interesting, fun, and innovative mechanic. Comically literal use of the theme. I could see you working this into a real, complete game; and it might not work too bad as one. That being said, though, the compo version is a bit lacking. Still fun to play around with, but lacking.
