The new sprites are still being worked on but they should be completed hopefully sooner rather than later... A new version containing the new CSS, new placeholder sign and life icon sprites, and the moveset rework should be out soon :)
Can't wait, well I can don't want to rush someone trying their hardest, but you know what I mean.
I'm really looking forward to this character Mecha Sonic has such a good design and he has pretty decent moveset so far, still getting used to his bounce, as it does get higher but not as much as other character bounces, so I have to change my mind set when using him, not that, that's a bad thing, it makes him different, although like what Iveary
Just a small suggestion, if his [shift] ability is his ground pound, maybe make a small damaging aoe around him upon hitting the ground with it? (Like super knuckles, for example.)
said I think Mecha should have a small damage aoe around his bounce, mainly because it feels really powerful move when you use it but when you use it next to enemies if you aren't touching them they are unaffected, which kind of threw me off, nothing to big, but can get a small cluster of enemies around you, as the super form does have that, but better in everyway.
But overall is still good ether way, looking forward to future updates.
But I don't want bother you to much with suggestions, Good luck!
