Decided to make a game about a little reaper collecting souls. Here's the art I've made so far, which took about 3 hours.
Going from left to right, top to bottom, there's the walking animations for the Little Reaper with no mask, with a mask, and with a scythe.
Below that, there's his death animation, losing the mask, and losing the scythe. The mask and scythe will be like power-ups (equivalent of mushroom and fire flower respectively, though not ranged). Finally, below those are the animation for the scythe slash, and the souls you'll be collecting along with it's collection animation.
