I've tested ALL OF THEM, they are all possible! From my experience: The Jumper is the easiest, just spread out your jumps on long jumps. The Float is second because it is really smooth moving which can be good. The Sprinter is easily the hardest, because it can jump really far, but it is reeeeeeeally difficult to get used to the jump speed-multiplier. Go to my (@bwinder) profile to see other cool games that aren't nearly as difficult including the famous SMASHY BIRD!! Like, Fave, and Follow if you enjoyed!
