A really good hack I loved the zones and the music from the prototype that didn’t make it into the final version of sonic 2 the only thing that lets this hack down is the final boss

While it's a great concept for a hack, the execution is pretty mediocre. I can tell a lot of work was put into it, but there's a lack of polish that makes this hack hard to recommend. There's a lot of blind jumps and leaps of faith that sometimes lead to a death pit. The enemies don't seem placed very thoughtfully either. There are also brutal sand pits in the first zone that lead to instant death and are hard to avoid at high speeds.

I do appreciate that some of the levels are drawn from scratch or recreated from screenshots. However, it's sometimes hard to distinguish foreground from background elements. This is especially a problem in Wood Zone where it's hard to see the hanging vines needed to progress.

If you play this hack, I recommend using save states. The Special Stages seem to be the same as Sonic 2, so I didn't bother getting all emeralds. The levels are hard, but not hard for the right reasons. It's not the worst I've seen, but I've also seen it done better.

This is 6 zones with 2 stages each, the quality and dificulty is about the same as the original game

Pretty Sweet

is this made from the ground up or does it use old never used levels?

why wont it work i just got it

how do you get to sonic 2: the lost worlds?

I Like dis

This hack features all of the zones that were cut from Sonic 2 during development. Some zones have been ported from the Sonic 2 Simon Wai prototype and then finished up, and some have been created based on magazine pictures and information from interviews with people who worked on Sonic 2.
