Hey, I just created an account to tell you that this mod is awesome. Definitely the best way to experience SOR1-3 IMO. I love all the additions that make the game play like SOR4. Since it's still a beta, I understand that balancing might be off, which is why I wanted to toss in my 2 cents:
1. Juggle is very cool to have, but so far the only character i was able to juggle with is Zan. Couldn't really hit anyone in air with others, unless by accident. Perhaps due to character's reach or the fact that enemies aren't launched as high?
2. Some bosses are really frustrating to fight, as they have very little openings and contantly attack/grab/counter. Examples:
- Jet (most of his attacks can be blocked, but he's very elusive/hard to hit as he doesn't seem to hover near the ground at all)
- Zamza (I understand that he's supposed to be fast, but I think he's way too fast and aggressive for normal difficulty)
- Abadebe (hard to even describe, basically got wrecked and lost a bunch of lives)
- SOR2 Jungle finale (I appreciate that we no longer have to fight both Jet and Zamza at the same time, but 3 bosses back to back is tiresome - I think that Harakiri was kinda uncalled for)
I dunno, maybe I just forgot how hard SOR2 bosses were because it's been years since i've played it, and SOR4 might have spoiled me with its fair bosses with no cheap sucker punches.
Either way, their behavior wouldn't be as annoying if they didn't have like double triple the health as usual

I mean, it's not like they're unbeatable, but the player is bound to lose a bunch of lives.
That's all I managed to beat so far (and SOR1 too), will update you in case any further bosses seem unbalanced (hopefully that won't be the case

)
Keep up the good work, king!
