It's a very good game, well done!
I love the art, and it's really well made.
There are however a couple things I noticed that could've been done better (this in no way takes away from how good the game is, I just think it's good to be critical, so everyone can improve, someone telling you your game is good is nice and all, but you don't improve from it).
So my critique here is that the audio could've been done a bit better, the sound effects are nice, but also a bit too loud (in comparison to the music) and sometimes feel a bit out of place (for example: the sound you hear when you click a button is a bit too high pitched and a bit annoying).
The thing I did love about the audio though was the sound of the sea in the background, that was incredible and felt really nice.
Other than these small audio issues I thought this was a brilliant game with brilliant gameplay and brilliant art, well done!
