You ever have a diamond in your hands that plunges in beauty due to tons of small cuts? That's spark 2. The basic go-fast gameplay is pretty fun, with alot of options for mobility, shortcuts etc. But the lack of visual clarity harms the game a ton. Whether its getting lost in levels, getting hit because of hard to see/know about hitboxes (EG a laser still hurting you as the particles dissipate, the flame hitbox extending upwards past where it visually is), or the bosses demolishing you since you have barely any time to know/react to their attacks, leading to most fights being a spamfest where you mash the parry and dash button. Soundtracks pretty good at least.
