Spectacular...
this has got to be the best i've seen in newgrounds like what all the others had said. it's as if i'm playing this on nokia's n-gage (don't have one though) and it still rocks even though it's kinda slow.
but there are still a few bugs here and there and somethings missing from the game: special abilities for sonic and knuckles are not there (not sure for knuck, but sonic's a definate no-no), there are no powerup monitors, no check points, you don't get temp invulnerablity after losing your rings... yeah, i think that should it it. oh and the robotnik's bomb machine for ice paradise is just too impossible to beat... managed to do it with tails and cream only.
anyway, it's still a damn solid game, and yeah, since this is a new release wouldn't expect it to be exactly like the real thing... but said above is just the stuff needed to make this game almost perfect.
oh and if you manage to include bonus stages + chaos emerald stages, you've really out done yourself dude.
keep it coming!!!
