You are entering the vast cave area. An ominous figure approaches from the shadows towards your party, mumbling unrecognizable words. What would you do?

I feel that 2D platformers struggle to find their place among players today.

Mech design? To be honest, I don't know what I just drew. Let's say, it's something sci-fi :)

In my head, necromancers (or sorcerers) are not raging beasts :) But maybe you are right - maybe there is "something" missing. Perhaps changing his pose to show him casting a spell, and adding some raised zombies and skeletons, could further enhance the character design.
