Mafia? Zombies? Gold spork?
Just tried out this mod, it's fun and plays really well even if the levels clearly aren't designed around modern Sonic. I have a few suggestions though:
1. Give Modern Sonic more interactions with shields. I like what's done with the elemental shield (fire trail when boosting and stomping), but the rest of the shields only seem to have their regular passive abilities, which makes whirlwind effectively a pity shield unless I'm missing something. Maybe make it so all shields adjust the existing player abilities? Like attraction making the homing attack more momentum-oriented, or whirlwind increasing the power of the double jump. Armageddon's ability could perhaps be integrated into the stomp (EDIT: I'm dumb and didn't try, it already is), and as for force, I have no idea what to do there.
2. Add an icon to extra life monitors and a life icon to the save select screen, instead of the default placeholder "1UP".
Believe It or not, the whirlwind shield actually does what you suggest. It increases the doublejump height and additionally removes the air drag Modern Sonic experiences.
