The level design is really not complementary with the gameplay/mechanics.
Tedious life bar combined with timer and amo pickup.
Long timer means that you start again fucker when you fail, loosing up to sixteen minutes.
Exits to the levels through which you can be dragged by cars, making you start again sucker.
Ennemis that appear as you progress, practically locking you out of some objectives if you do not know the proper order you should be completing them in.
Levels that can't be finished with some characters because of their stats, but it won't tell you that.
No restart button during the long races, you wait or you go through multiple load screens.
Absolutely no defense against ennemis that plow you as if you were a running back (had to look it up).
Floaty, unresponsive controls that make it very hard to land where intended.

Makes it one of the most frustrating and punishing game I ever played.
Still.
There is something to it that makes me like it, even if it's mostly grating.
And it's fairly short, less five hours even if you suck at it.
