Toucharcade: Steampunk-themed programs have done pretty well on the App Store. Games such as Gears have certainly demonstrated the viability of incorporating that sort of fantasy/mechanic aesthetic into a game. ArkanoArena is the latest game to incorporate the fantasy/steampunk motif, this time in a brickbreaker. While I think ArkanoArena definitely nails the steampunk visuals, issues with the controls may turn off some folks.
ArkanoArena is definitely one of the best Arkanoid's and definitely have the best graphic design.
