Why not? Rush's gameplay is so simple it barely took me a week to make. No need to let ideals get in the way if it's no skin off my back. Servers can lock Rush Mode if they want, and they can't force you to use it.
Not
quite what we said. SA-Sonic's always had Sonic Advance influence due to a bias on Metalwario64's end. We settled for "Adventure Sonic" because Advance's gameplay translated
TERRIBLY to SRB2. (
Even a perfect copy of Adventure 1's physics translated badly. Imagine the current airdrag and floatiness tripled, groundspeed even faster, and jumpheight doubled.)
It
IS true Rush was initially Advance 4, even using Advance sprites and Drummond's voiceclips. That bit of trivia made Rush enough of a spiritual successor to feel deserving of an SA-Sonic easter egg. Considering how naturally it controls with SA-Sonic, I'd say it worked out! And if all Modern's identity boils down to is just another Advance game's gimmick...eh, not our problem
You sure it's a generosity problem, and not just rings refilling the gauge that feels off? All
Rush Mode speedruns I've seen have Sonic
barely hanging onto a single bar, swerving for every ring/enemy in the way. In Sonic Rush you're near max-gauge all the time if you actively try to uphold it.
I
did make rings fill the gauge unlike Rush, mostly since SRB2 doesn't use springs/ramps as often as Sonic Rush, and giving SA-Sonic a full-fledged trick system was beyond Rush Mode's scope. I didn't even intend to get Metalwario64 involved, actually, but he got so excited seeing the progress he
immediately made Humming Top sprites.
Yeah, that transition period is
the biggest reason it's so subjective when Sonic shifted from
"Adventure era" to
"Modern era"
Unleashed's design
existed already in Heroes. Nobuhiko Honda's design, I believe. Yet Advance 3, the Rush games, Sonic X, and '06 mainly followed Uekawa's design. Even Brawl, Rivals, and the Storybook games took hints. It never shifted all at once.
Nowadays, Heroes' design seems to be the base. Even Uekawa himself is now slowly adjusting his art towards that. Modern Sonic also reuses anything he wants, not just Rush's boost, so things are too muddled. People base whether Sonic is "Modern" or not on the boost's presence, who his English VA is, how he's written, his spine length, his height, his shade of blue, etc.
All arbitrary, subjective things. By extension our choices will be too. We did forgo perfect Adventure physics for something we thought would fit better in SRB2, after all. We never claimed to take no liberties. We only aimed to have the closest look & feel to Sonic Adventure SRB2 has gotten.
Rush Mode was so easy to make because locking the Spindash + Bounce locked almost everything else away too. Allowing all moves at once would be MUCH harder to program since there's so many potential combinations of things that can interfere with each other.
I also don't want extra custom buttons for gameplay, or see people lean off from the main playstyle just because it's less powerful
v1.8 SHINING ALPHA TEST SERVER:
Btw! To prevent the return of The Milne Chronicles™, I'm hosting a temporary Discord testing server to make sure v1.8b gets all the QA it needs before it's official release! If you are up to do some preliminary bug hunting for v1.8b, come on over and apply for testing roles!
https://discord.gg/invite/GdAwcGYJ
I'm leaving home right after this post, so I might be gone when you apply, but don't fret, the testing period will be several days long.
