The art looks nice, and the music are nice too. The gameplay is interesting, I like the water mechanics, the way you need to balance it with enemies bullets and reload is really cool. The bosses are nice too, personally the second boss feel more difficult than the third boss because of how much water it has per attack.
Tho I found that I the third weapons is the best when fighting the first boss, second weapons is for the second boss, but the first weapons dont really have much use.
But still, nice game!
