I've been working on this on-and-off for around two years for the same reasons as Super Minio Bros: I couldn't find any other resource packs that fit this theme that were both updated and to my liking. Although, unlike Super Minio Bros, this pack actually looks good.
If you are wondering what some of the mobs are meant to look like, check the actual texture; they all have a picture of the actual sprite on the texture somewhere.
This pack also supports all of the blocks in the 1.8 snapshots.
