Has everything, and yet nothing.
In theory, this game should be great. The graphics are polished, the gameplay is somewhat innovative, yet it's boring and annoying as hell.
Lets see:
The only actually new game mechanic was the rotating crystals, which to be fair isn't actually new at all, and is generally underutilised in the game anyways.
The game is hard, but not challenging. Most of the time the issue is the black holes, which is actually really boring and repetitive. The bombs aren't particularly useful when they're NEEDED, and when you're able to take the holes out in advance, you're able to avoid them anyways (and from what I saw, sometimes they RESPAWN, making it entirely useless altogether). So that leaves us with the "lives" mechanic (annoying and unecessary), the "collect the trapped crew", the "collect the coins", the ship, and the annoying enemies.
The coins forces you to run around the level and go out of your way, which is annoying and repetitive since you have to keep avoiding the black holes, the "collect the trapped crew members" is unnecessary for game completion (the COINS should be the unnecessary goal, dammit) and fairly rare as well, and the black holes are boring and annoying.
The most memorable level here was level 19, "the path of desperation" or something, which isn't particularly interesting on the first attempt, and tends to require split-second reactions (meh) or memorising where abouts to dodge the fireballs (which is repetitive and boring).
As for the story, there's enough of a story ("get on the rescue ship and bring coins + other crew/passengers/whatever") for you to wonder how the hell you got there in the first place, and what the hell you're trying to achieve. It's not explained, concluded or lampshaded. Not cool.
Also, for anyone looking for a challenge, it isn't THAT difficult to finish, it's just boring, and after you've completed it, there's no "challenge" after that. So from what I can see (story gamer, explorer gamer, challenge gamer theory etc), it's not that appealing to anyone except those with low standards.
The good news is that I couldn't find any glitches, and as a program it's fairly decent, if uninspiring.
