I just released an update, so now there's a defeat condition! I know the game is slow, but the physics are difficult to design.
There are also some known bugs, but I don't have time to fix them :(
And now you can use "P" for pause.
Nice, I think adding a defeat condition was a good choice. Fixing bugs can be very hard, just hang in there and you'll get better at squashin' 'em :)
