I really enjoyed this hack. The difficulty curve was not to steep in comparison to ZM. I got all the upgrades but one expansion (grrrrr...). Kraid was as difficult as in ZM, same with Ridley. Also, I really liked the recolor of the suits and the cheeky explanations of the items were funny. The enemies were recolored spectacularly and Meca Ridley and the Motherships rainbow flashing reminded me of super Metroid, which was awesome. And the tile choice DEEPLY moved me.
Really good hack with great music and customized graphics, BUT too much backtracking for my liking (even with the shortcuts), Ridley was not fun at all, and it ended way too soon.
