Progress thus far
Well, I think I’m being too ambitious with this concept, yet again. Nevertheless, it’s probably one that a number of people have thought of: use multiple instances of yourself to defeat the enemy. In this case I have three different instances, each being a different class with unique abilities and weaponry. I’ve spent a lot of time on the code and there’s still more to do, so I hope I have time to make the game a bit prettier.
Anyway, here’s a screenshot:

A replay with all three classes.
