Incredible idea, but just too difficult.
In all games we can see a correlation between difficulty and challenge. Most game developers try to make their games difficult enough to represent a challenge, but not exaggerating, otherwise making player feel frustrated.
Said that, I can plainly say, that Ignition went wrong with this game, the game is just to f...-ing difficult. First levels and labs are fun, fast, you must fight against the clock but not having to cruise impossible obstacles over and over again. But later levels are just impossible to accomplish, even with a 50% of mercury.
Anyway, the game can be "finished" after long retries and effort. And after all the hard work, you just unlock the last lab and.. that's it.. more levels, skins are not rewarding enough to even try playing those insane last levels. So sum all that up: Almost impossible levels + sucky ending = frustration.
And.. enemies, the AI is plainly stupid, go to player, then eat/blow it, and worse is that there is now way to fight back, or avoid them successfully, they're too fast.
It's sad, a very nice game, but surely is a game that's not worth replaying, or finishing either. Graphics:
Graphics are nice, are just great. That comic style fits with the mood of the game.
Sound:
Soundtracks are not good, nor bad, very forgettable. Value:
Manipulating a ball of liquid mercury around platforms, changing states, temperatures, magnetism, switches? Very cool concept for a game, but game developers should have aimed to a more "occasional gamer" than a "hardcore gamer" public, and throwing some rewards like "slow mo" pickup, or "undo" skill, I don't know, but any of those two, could've been great.
