This is a very impressive hack and I had a lot of fun playing through it! I thought this was going to be very easy based on the first 2 levels, but the difficulty did ramp up and there are some pretty challenging platforming sections and difficult stars.
The skill level ramps up pretty quickly, but I never found myself thinking something was unfair or too difficult (I now see what the intended strat was for Crystal of Khione, which would've saved me a lot of time & frustration).
It took me about 10 hours to 100%, but more skilled player could definitely finish it quite a bit faster. There were a lot of fun easter eggs and the guest levels/hall of fame were excellent. Also
idk if the blocked ancient door is ever supposed to open, but I never got it to.
My only real complaint is that getting out of the lava overworld is frustrating if you don't unlock the metal cap right away, but that's a minor QOL thing and is far outweighed by the creativity in this hack. Really great job on this, I'll be giving it another playthrough very soon.
Wow, I love the concept, I love the OW, I love the hang mystic mansion level because is it a mix of my 2 fav Sonic Heroes levels and I miss that game so much and the music remake of this level fit so much great!!
Just to let you know, Kaze's SMWCentral account is called Kazeshin, and not just Kaze (you've linked someone else's account that's seemingly dead). Also, I *think* because his name is on it this is going to be rejected, since SMWC doesn't want to associate with him any more, but I'm not 100% sure on that.
