This is my entry for Minigame Comp #22: Transformations. Use Wario's bulk strength combined with Mario's jumping talents to endure your way through a challenging obstacle course.
A story? Meeeh, if I had to, I'd say Mario and Wario must use an ancient medallion or something of that sort to escape a colorful prison setup by a mysterious villain... er, that good? ^^
To change characters, press M while Wario to change into Mario, and vice versa using W. Jump is Shift (although this can be configured otherwise) and run/charge-dash is Ctrl. Good luck!
KNOWN BUGS: Clipping issues. Just shut up about them, I'm aware they're there, and there's nothing I can do otherwise, so neugh. Also, you can force Mario into the same limitations Wario has during his charge attack by pressing M when you're using it, so be careful with that. Just press W as Mario to remedy this problem.
EDIT: Well, it won second place! Woo!
