Pretty easy game. Jump on the ghost's heads so you can not be posessed. The hard part is waiting for the right time to jump onto the higher parts of the screen.
So - i know this is an OLD game, but in zone 18, i left the game on for 4~ hours, and the red cell that was behind the wall moved inside the wall. I couldn't attack it, but it could attack me.
Nice little game, from what i see so far you might want to add more rings, maybe have ther percentage text in the middle be for the furthest ring. Also, a bug: sometimes on right clicking and then left clicking on the game, it likes to fast-forward distinctly further than it shouldve gone in that time.
You don't connect the windmills to storage, they have their own battery they need to be connected to that uses steel. Try the Accumulator just before the windmill and wire, works like storage but ONLY works for energy.
