I tried to finish it but it was getting too frustrating. Fuel is too limited. I think you were going for some kind of hardcore, unforgiving Ninja Gaiden difficulty, but the controls aren't tight and you can't even boost horizontally.
Perhaps some check points or a series of small levels would have been nice. Having to restart from the very beginning after getting through tough parts was demoralizing. At least start off with some easy jumps and gradually move up to harder areas.
Graphics were nice though.
