First played this in the arcade and ended up getting it for the SNES. Multiplayer is a lot of fun to play with friends and you really do have to find the best way to keep your walls up around your cannons. It can be hard to come back after you are down a few cannons to your opponent. It's not pretty and you move along each square so the controls are straight forward.
