Fireball 2

Fireball 2 is an elegant and satisfying arcade-survival game about dodging swarms and triggering bombs. Take control of your fireball and weave through the massive flood of enemies. Lure the flood towards bombs and trigger them, either directly or indirectly, to take out as many enemies as possible. BOOST, NOVAS AND UPGRADES In Fireball 2, the controls are easy to learn: Move with the left stick and boost with any button. Your boost is unlimited, but using it constantly is not always the optimal strategy, as you are forced to move at max speed while boosting. The faster you move, the faster the flood of enemies react and pursue you. After destroying enough enemies, a Nova is created from their sparkling remains. These Novas not only unleash a large explosion, but they also upgrade your fireball. No need to choose which upgrade you want; your fireball becomes bigger, faster, AND tougher with each Nova you unleash. Level up your fireball to max power, and every Nova becomes a SuperNova
