this series is all about asking simple questions
for the first one the dev asked : what if sonic 2D was cool, and then went on to answer that question.

then for the second game he dared ask : what if sonic 3D was not only cool but functional too, and then went on to make an amazing game that its so responsive and balls to the wall fun that i still cannot fathon it actually exists.

then the crazy dickhead went on and asked : what if spark 2 was epic ? and went on to make one of the best games i've played.

somehow its even more responsive than the second game, its a perfect sonic game, it doesn't restrain you, it doesn't scare itself and lock you into a straightfoward momentum or a pseudo game cutscene, or jank you into clunky deaths that were never your fault.
no, this is a concise, straightfoward and confident game that will deliver mechanics you can rely on, and challenges to put those mechanics to the test, and not once did they fail me, even at the absolute gauntlet that is the last level (that you gotta beat with limited lives, for once i like limited lives).
story wise it tries to hold itself but you can clearly see the bonkers going on in a larger scale, but this time its a bit more well developed, even if it still goes dragon sonic and the sevel jutsu balls revengeance, i love this game, if this game was a man, id let it go to bed with me.
as a bonus the dev even ported all levels from spark 2 into this one with all the perks of having a upgraded mechanic and movements, the delight of replaying these is unmatched

are there problems ? sure, not being able to remake the keyboard controls is silly, forcing some levels in order to prgress, lack of last power ups, a not so great last boss.

but i'm willing to look these as just rough parts of a diamond, this is it, the perfect sonic game. no, spark made its own identity, now sonic has to keep up if he wanna prove he has quality over spark
