Overall 4/5 = I liked the game! Everything is clean and easy to play. I got relaxing vibe maybe because of soundtrack. Sometimes was frustrating to defend ship and that same ship was destroyed be a mine at the edge of screen.
Graphics 4/5 = I liked clean pixel art graphics, multiple kinds of boats and monster was cool too.
Sound 4/5 = Sounds were really relaxing, it have that vibe that you are in the middle of ocean and just peacefully help other people.
Innovation 5/5 = I never played anything like that, so for me 5/5. I liked the mechanic.
Fun 3/5 = Great game, but after a few boats you need to constantly wait for spawning another ship. It would be cool to make it harder/more dynamic in time. Or maybe it is and I didn´t play enought.
