@SRB2SuperSonic review I quote:
"This is a fun mod to use, but there's a lot I have to say about it. And not much of it is nice. First off, I like how fast he goes, but he's a little too fast in my opinion. Second, his moveset can be expanded to include more modern abilities like the Light Dash and Bounce Bracelet and even the sweep kick from Sonic 06. Also, this is probably the first modded Sonic in SRB2 to not include a Super form. If you can implement that, it'd be appreciated a little more. Also, there's either incompatibility with BuddyEX, or I just don't know how to spawn a Neo Sonic bot. I hope this gets looked over and some of these changes I mention actually happen. Thank you."
1. He does have compatibility with BuddyEX. His spawn code is "addbot msonic color", and if you don't know Greeneyes, it's "addbot greeneyesonic color", with Modern Sonic being "addbot modernsonic color".
2. Yeah I agree, he could use a bit more moves, with (most of) them being the ones you suggested. I'm not criticizing him, but still. I only suggest a few extras: Super Peelout, some sort of combat like ability, and a double jump.
Now on to my actual review: He's very nice to control, albeit being slipperier and heavier, I would like it a bit more if he was less slippery and heavy, but if that's the point, that's cool. Also, he feels a bit more empty since you removed shield abilities being stacked with the Dropdash. Adding them back would be nice. But criticizing aside, He's a very good character, almost like SonicRE (with Bounce Attack replaced with Dropdash), but not nearly as complex to control as say, oh I don't know, GREENEYES? But still, this is astounding, and I give it a 10.5 out of 10.
