2 cannon abit too much no? a small but strong cannon seems very good. Since guns are basically a small hand-held cannon! OwO
If i hand an option, i would definitly make a spike cannon ball or a cone shaped cannon-ball(coned)
The only reason I say 2 cannons, is when you shoot one cannon, it might sound lame. 2 cannons is 50% less lame, at least. One of my favorite parts about the Carrack is that it goes pew-pew-pew-pew-pew-pew-pew-pew-pew
