So, uh, screw this game. It's fun for a while, but then the physics puzzles hit terribly. Balancing is NOT FUN at all (not to mention it makes it an ACTION GAME...). Especially since it doesn't give you any tools to deal with it, like a grid or even being able to see the center. Once it even starts to get off-center, you have to restart really because it just goes and destroys everything.

REVISE: So it's really just that one "ruler balance" level. A later balancing level was... reasonable. It's getting pretty repetitive now though. I'm about 2/3 done according to the list of checkboxes.

REVISE2: Completed all goals in all stages. It's really just that one level that's a PITA. I managed to do it after looping back at the end of the game. A couple stages took a bit longer for sub-goals than I would have liked, but, overall, not a bad game. It didn't overstay its welcome. Much longer and it would have. Also the achievements list is, as always for pretty much every game with achievements, stupid. And a few are bugged and didn't trigger even though they did.
