CASTLEBOAT is a card-based tower defense game about building an insanely tall tower on the deck of your ship and using its weapons to protect the world from sea monsters. It’s a castle...on a boat……….(title pending).

it would be nice to have a somethin to tell you how to shoot

love it love it want more of it! Jack's music is amazing as always

Also I super expected to be able to use the mouse and it was weird that I couldn't

I enjoyed the battle system. Took me a second to realized what was going on at first. There was quite a bit of dialogue, but thankful there was a way to skip them.

Too much dialogues, need to redraw much sprites.
