When an energy link is destroyed, another link should be formed, if possible. Otherwise, multiple energy links should be created for objects that don't deal with energy, rather than just the one. Also, miners should be able to go over energy links as long as they aren't blocking the -only- link to another object. And when that miner is destroyed, the link should be restored.
4/5 for original gameplay and good music. Replay value is next to nil so it lost a point... (This is the account that should have gone to; the other is my brother's)
Perhaps you are also supposed to not let the shapes pass. It is still not a great game, but at least that explains the game over thing. It should reset when you choose to restart, though.
