Which to cancel.
Well, it really depends on how long the jokes in Java take you to come up with.
If they just flow out of your mind, then dropping Java is silly.
If the Java story takes lots of time, then drop the jaguar.
Kickman is probably your most time consuming work.
Most story accuracy. Most dialog. Most drawing.
I guess that Hive Valley would be the same amount of work, but that gets you 6 days worth of material.
My favorite is The Real Superheroines of Hive Valley (and most upvote per time drawing)
Next is Java (because it is really simple, and a certain cat has a claw at my back...)
So, i would drop Kickman. Its a good stopping point, but i will very much miss it.
