I enjoyed playing this hack quite a bit, although it's not finished, I'd say it's pretty good. There are some remixes using Super Metroid's sounds, but 2 of 3 are ones I like. I never felt the need to look up a walk through, or maybe I just happened to bomb the right areas to find everything, although I've not gotten all the items, it's not necessary to get all of them to beat it or make it easier. The physics changes weren't great but they weren't bad either honestly, I didn't have much difficulty adjusting to them. There seems to be no required order for anything almost, but obviously some areas will be locked off until the proper upgrade is acquired. Another thing is that no advanced tricks or techniques are required to beat this hack. Good work Jefe962.
Note: My time is bad because I had to do some backtracking to grab the remaining chozo keys+items, but I enjoyed it nonetheless.
