One of the most unfair games I've ever played, it's really, really hard, but for all the wrong reasons, one of them is that the level design is highly dependent on RNG, so you could have done everything correctly, but because this is basically a racing minigame, and each time you do a lap, you get a random hazard, some of them are easy to ignore, or even benefitial in some cases, but there's also a lot of them that can be run-killer because of how absurd they're, and they're all decided (except some fixed ones) by RNG, so you'll have to redo a lot of levels just because of bad luck, how great.
There's also the fact that there's 2 "health" gauges, the health gauge itself, and the fuel gauge, which if it ever gets to 0, you die, this is specially fun because if you touch the ground, even at lower speeds, you will lose health, so the only way to not lose health is to fly, which wastes fuel, so you have to optimize the use of fuel to beat almost all the levels.
In the end, I had to do some minor "hacks" in order to 100% the game, since the save of the game is a text file that you can edit to activate flags such as level beaten, in my case, I had to deactivate the one that registers if you triggered easy mode, since I think that there's some levels that are just impossible to beat on normal mode.
