I see one problem with ALL ability2 things.
If you don't have spindash, or an ability that has about the same properties in ways...you CAN't slide under a tight spot or break a wall, blocking the level's progress for many custom characters. Isn't there something that can be done about that?
And I'd say...
-Jumpanims-
0: Simply spin.
1: Go into your spinning animation when going up, and into your falling animations when you're falling.
2: Spring-up animations when you go up, into spinning frames when you fall.
3: Same as nojumpspin. Go into your spring-up animation when going up, falling animation when you fall down.
Waterskip:
Same as in 1.09.4. Had both it's advantages and disadvantages when chosen.
Superpeelout:
Already requested, I think. Charge up, charge time being slightly longer than the spindash, and then zoom off at speed 60 or 50 or so. You maintain your speed untill you hit an obstacle, wall, jump, or brake. As long as you're "superdashing", you can run over water, unless waterskip is set to be 0. It's an ability2 thing, and can't be used unless you stand still.
Endcolor:
Always a good thing to keep in optionally, as you can set more than 15 colors if so is needed.
