All in all a nice game. But the shots of the canon are too dark.  I can't see them =/

I like the sprites that you made, they have a really distinct style that i really like, though they could do with a bit of animation. The game needs a little polish too, and i'm not sure, but are you supposed to be able to just buy the bigger cannon from the beginning? and does it make any difference anyways? oh, and one more thing, i don't think i've ever seen an ocean look so cute!

Hello, I really like the smiles on the waves and the Moon :D And also I like your art style with thick borders. I am honestly not sure if the weapons are doing anything different from each other or they just look cool. Keep it up!

Could use a lot of polishing. You could think about including sfx and maybe some kind of music to the game. Besides shots is very hard to see, so maybe a lighter color for these would be better.
