No actual new version yet, but for the past month or so, inspired by others:
I decided that I'm going to refresh the pack. Mainly through learning about slight shading and anti-aliasing, and the general inconsistency of the sprites in this pack, I'm going through each character here (except for Puggsy, who will be removed in the next update due to the Combi-Rings version being VASTLY superior), and respriting them or touching them up.
The first part of the refresh will contain Wilkins and Monkey as well as:
6, 3
7, 5
6, 6
3, 5
7, 1
2, 1
And two newcomers. It'll come when it'll come.
