For Sonic,

· Add red rings/emblems to find in the stages, to add actual incentive to look around at your surroundings and explore. (Actually, do this for everyone.)

· Restructure the stages to have more open sections, similar to the that seen in the at Dawn section in Speed Highway or the Lost World piece that Sonic shares with Knuckles

· Restructure the stages to have more wallrunning, and way, way more platforming.

· Remove Casinopolis, or change it from a pinball level ti a pinball/casino-themed level.

· Better yet, just look at Sonic Robo Blast 2's level design.

· Make Sonic's jump less floaty and to where it maintains more momentum.

· Seperate the light speed attack and lught speed dash onto different buttons (or remove the light speed attack, as it's useless.)

· Seperate the homing attack and air dash. Or at least make it to where the jump button can do both, but another button can only do the air dash.

For Tails

· 3 options. Make him a treasure hunter like Knuckles, give him his own levels that aren't trivialized by his abilities, or add more verticality to his stages.

For Amy,

· Either make her faster, or give her own levels that are actually designed for someone her speed.

· Make it easier to maintain momentum when turning.

For Big

· Fix the underwater camera so you can better see if you're hook is in the path a fish is taking

· Make reeling them in faster

For Gamma,

· Actually Gamma is fine. Heck, him and Knuckles might be my favorite playstyles in the whole darn game, to be honest.

· I don't think they should make the bosses harder. If they do, they should make it to where yous tart with mire time so you can comfortably complete his a missions.
