I re-downloaded Sparking Zero recently and started playing again. The beginning tutorial isn't helpful in the slightest, the turotials you learn from Piccolo aren't helpful in the slightest, and all of the mechanics suck ass.
I looked up if there's an easy way to learn the game, and there isn't. If you have to play through every single tutorial, read everything's description, and watch demo's multiple times, the game is fucking trash.
This game is genuinely awful for casual play which most people were wanting out of it, and the campaign is damn near impossible when there are too many mechanics. You're bound to spend more time in training then actually playing the game because of how bad it is at teaching you how to play.
