amazing game
well as a player im impressed cuz this game is allso a challenge and alot of fun, as a programmer im allso impressed. yet there are some minor bugs..
first the depth of the health bonus are sometimes bigger then the depth of the sea causing to the bonus look like hes outside the water, the other problem is the menu btns.. you forgot using onReleasOutside method on the mc cuasing the btn stuck on the over anim while the user press it and release the mouse outside the btn hitarea.
beside of that this is a great game, good job, honestly.
