I went with the standard, "Character looks at you as if to tell you that you're a n00b" animation. I had to do some annoying hacking at my jump code to get the little effect you see in such games as mario. The effect works quite well, though.
So, I decided on, what I consider to be, a better alternative to ladders in the game. Now, it might just sound like I'm being lazy (and that's part of it), but I think the alternative will be more fun than climbing a ladder. Basically, I'm going to make a spring board, like in several Sonic games, that when stepped on will propel you really high up. I think that will be more fun to use than a ladder(not to mention easier to program[grin]).
