It's like Time Fcuk...
...Only much less entertaining. And much less free as well.
There's quite a lot that could do with improving here, especially if you want people to pay for the rest of it. Most notably, the lack of any real urge to see how it ends. The storyline is pretty basic, from what these two levels would suggest. "Spaceship encounters some space-born weirdness; crew in danger; you need to go save them." ....Boy, that's about as original as using pixel art to create a pseudo-retro effect. I can probably guess the ending right now, and even if it's got a surprise conclusion or something, keeping it a total secret is not going to make people interested in finding it out.
The graphics were done deliberately in a basic style, so that's hardly a fault. There are loads of games on NG that do the same (albeit free ones). In fact, the colourfully simple nature of them was quite a nice touch in places that had moving backgrounds.
What WAS a fault was the time it took the flip / move controls to respond to you. They're simply not sharp enough for it to be fun, and although I did finish both levels, I must've died about 100 times in the process just getting past a few areas where the gaps you have to go through are outright frustrating to navigate with the sluggish controls.
There's also the set screens, and obstacles going across more than one of them. Some may call it a challenge, but personally I think there are better ways of making a game challenging than to effectively blind the player by only letting him / her see a set portion of the puzzle until they're flying headlong into the next part of it, with only a fraction of a second to work out where they're supposed to be going. Making the screen move with the player makes much more sense if you want to create large puzzle areas like that.
All the above put together made the game more of an exercise in trial and error than skill, and wasn't as much fun as it probably should've been. Sticking a price tag onto something like this (which is frankly worse than a lot of games on here that don't charge any money for their use) is an ill-advised move, IMO.
