Graphics
The art style was very nice. I like the fact that it's all tied together so well and that you don't rotate pixels. The only minor thing that bugged me here was the explosion that didn't look like it belonged in the game. Easily fixed, though.
Audio
Sound effects were there. Nothing annoying but nothing to write home about, either. The music on the other hand seemed to vary quite a bit an had a nice vibe to it. Very impressive!
Gameplay
I remember playing a game like this about 16 years ago that was on one of those demo cd-roms for windows 95. I wasn't a big fan back then and I gotta say that the idea hasn't grown on me since. That's just me. What would've made it more enjoyable for me is giving the player a bit more impact. I understand that the idea is that you have very little control and that you have to balance out every move really carefully. However, many times I let the craft fall down fast and then had to hold the W key down for many seconds to get the craft to do what I wanted it to do again. This gets really frustrating because you already know what you want to do, but you're just waiting for the craft to catch up with your thinking.
Other than that, the one thing that always bothered me with games like these was the fact that you have to be so pixel perfect with the landings. Again, I understand that that's the idea of the game. I'm just saying that when you've cleared the whole level and then mess up the landing by one pixel, it get's frustrating super fast. Maybe the difficulty of the game could consist of purely maneuvering the craft through incresingly more chaotic obstacles. The landing part should in my opinion be way easier.
Functionality
I don't know where the screenshots went. I tried taking three of them but can't find them anywhere.
Overall
Very nice little game. I wish the levels could be completed faster so you can concentrate on doing better and see more of them. I urge others to try it out, too.
