Damn it!.. that really sucks. I have been working on a game virtually identical yours for last few months. Though my fiction is that you are a newbie pirate and instead of island monsters, you shoot at target crates and monkeys run around and set up the target range. The same knocking over structures, with the addition of pulleys and ropes that have to be puzzled out. But the same traveling around an island(s), and though I have two gear wheels to set the cannon, I even have the ship bob like yours. The art style is even in the same vien. Though your art direction is very tight. I love the water and the bold colors.
Oh well, on the upside I just bought yours and can play it right now. Great game, fun and beautiful.
Damn. Now I have to rethink mine… completely. (but I’ll probably keep the monkeys).
Great job, these are exactly the games I love, and this is a shining example of fun physics puzzler.
