- Scrappy Mechanic: This game heralds the return of more classic features, such as the separate bomb bar and character-unique spell cards, but the UFO mechanic for this game proves annoying to many players, especially since using said mechanic is one of the few ways to gain more power, bombs, points, and lives. And by "one of the few" we mean "basically the only really effective way." Basically, some enemies will release a small UFO when killed, and gathering three small UFOs of specific colors will summon a big one, which then drops resources when destroyed. But these things will bounce all over the battlefield, making collecting them a pain in later stages. Further, there are color-changing UFOs which can change color just before you collect it, ruining your big UFO summoning plan.
