I am currently fighting a boss that is to the right of the map and spawns a ton of projectiles that slows down the game to crawl, as i'm writing this, it's still frozen, other than this boss, the game is pretty good and challenging. I just wish this boss was changed so it doesn't spawn that many projectiles and lags the game a bit less, this is the third boss i'm fighting, the others where running just fine, idk why this one slows down the game so much

I suck at this game, but it's really fun! I also like the goofy ahh characters lol.

I LOVE this game, i really do, it's fun, really fun! But there is one problem that i hope is very rare: The game detects inputs for longer than they're actually pressed, i may be taping the right click but it detects it as me holding it, i go up and it keeps going even after i stop holding the W key. everything else in the game flows normally, the enemies come at me playing their normal animations and the background is also normal. I REALLY hope you can fix this somehow.

Good luck putting all those wrinkles into a sprite!!!! LOL!!!
I actually do like the designs, it just has so many damn wrinkles, like, get some cream or something, damn!, dude looks wrinklier than my grandma. You'd probably save a lot of time if you didn't make your desings so wrinkly and used the wrinkles more for specific drawings, instead of being there by default, imagine animating something so wrinkly!
Also, i like the sonic sprites but the shoes seem to lack the upper part, at least in standing, idle and up looking sprites

TMG!!!!!!!!!!!!! MAKE SUPER SONIC BUFF, AND MY LIFE IS YOURS!! (i really enjoy me some good buff super sonic, it's so cool)

For eggy... First off, he needs a bigger body, i get it's like your style, but i feel he doesn't look as y'know, egg with them long ass legs. I feel B's jacket look is a bit too complex, however, if you put B's scarf-cape, logo and the shines on the boots on A, it'd be a really solid design, or maybe mix both of the scarf-cape designs. Suprisingly, i think B's pallete works better if he were to be side by side with Sonic, i think it'd be a good contrast.

I like the re-addition of Espio's rounded shoulders, tho, i fell you missed by not just straight up giving him his classic design face with an eyelash or whatever, it's kinda what i did for my own modern espio redesign (https://www.newgrounds.com/art/view/santinoainthere/modern-espio-redesign), You can try that out in some of your doodles, still, pretty nice stuff even if it's an old drawing.
