Colors DS has a different set of Wisps compared to the Wii version which while both has the same wisps such as Cyan Laser wisp, Yellow Drill wisp, and Orange Rocket wisp just to name a few. Each version has wisps exclusive Pink Spikes wisp, Green Hover wisp, Blue Cube wisp and Purple Frenzy wisp all being exclusive to the Wii version of Sonic colors while the Red Burst wisp and Violet Void wisp is exclusive to the DS version of Sonic colors.
I should mention that the chaos emeralds are in colors DS, 6 six emeralds are straight forward to get, with the end goal being get 50 rings then reach the goal and complete the special stage. Where things get a bit awkward is with the last emerald where you select game land then win the race against the computer player while having 50 rings.
Moving on The bosses are the weakest part of both games actually aside from the first three bosses which are fine (Tropical Coast, Sweet Mountain and Starlight Carnival) While the later bosses are kinda just repeats aside from the final boss Nega Wisp Armor in both version and if you get all of the emeralds in the DS version only you'll get the mother wisp boss fight which I find to be alright, It wasn’t boring like the Egg wizard in Sonic Rush Adventure but it doesn't excite me as much as the Egg Salamander in the first rush game. The DS version does have more engaging bosses than the Wii version so it has that going for it.
That's about it for Sonic Colors DS, this ended up being excellent game all around, I give it an 9/10. That's about it See ya.
Oh as an Bit of side note about Dimps, it's quite ashame that Sonic colors DS was Dimps last good sonic game because what came after are games that are mediocre such as Sonic 4 Episode 2 & Sonic Generations 3DS or be terrible such as Sonic 4 Episode 1 or be the most fuckass game to exist such as Sonic Lost World 3DS as a primary example. Sonic Lost World 3DS being Dimps is last Sonic Game they have developed to date which is honestly a pretty terrible note to end on on things considered.
