Warship Elemental (Draft)

This is a draft of a sea style dungeon crawl where you control a warship that can shoot elemental cannon balls. At the moment you have access to all cannon ball types (fire, ice, poison), access to unlimited ammo for all cannon ball types, access to all the areas, and access to none of the upgrades for your ship. Death simply restarts the level.

Note: This is not finishes, but feel free to leave you suggestions.
