The game is OK imho, everything works
A minimalistic tutorial-screen might be a good idea once you have it more polished, the gameplay is not difficult to grasp, but the lack of visual feedback hinders the user from instantly “getting it”, for example the selection could use some graphical feedback, like a red outline around the part when dragging it, etc.
The ship parts are hard to see, not only because of the water being not very translucent, but also because the ship parts do not have a contour that’s really standing out, sure they have sharp borders, but their texture/tone/color does not change towards the border, which decreases the visibility of the parts, plus they get stuck into each other.
It’s a pity the parts don’t collide with each other, would be a nice effect when they’re floating on top of each other.
The screen getting dark triggers a bit eagerly sometimes.
Otherwise thumbs up from me, the little ai-guy moving around to stay on the boat is pretty nice.
Oh and holy shit, 228MB??? are you microsoft by any chance? Releasing a desktop version for this game with an embedded JVM and all that jazz is not necessary, nobody will play this mobile-game on a desktop, you might as well upload a *.jar with only the code and assets since the people here all have a JVM installed.
