Gameshell workaround: supernova://play?swfurl=http://chat.kongregate.com/gamez/0004/8761/live/Use_Boxmen_kong_.swf
Puzzles games should almost always have a stage select.
This uses GameShell, which is broken on Supernova. Workaround:

There's also the download link if you have a standalong player.

This one doesn't run in Supernova, but works fine if you download and can use a flash player.

Game doesn't launch in Supernova, requires fiddling in Pale Moon's console to get it working. (Manaully using swfobject.embedSWF)
