I've been playing and there's no difficulty past easy- a little disappointing. I think that the water needs to be more viscus. Overall the it is a great puzzle game.
Reviews for "Gravity Water"
The difficulties above "ease" should be available. It's pretty much a waste of time with the given difficulty, and there is no known way of activating harder difficulties.
shockwave flash has crashed :/
Not a bad idea, and good water mechanics, but the game is buggy and crashes often. You can also easily cheat by smashing the water with the plates, which often bugs the water out of its trap. And only two of the difficulties shown are actually working, which is weird. Needs more work
The graphics should be clearer - I replayed the first level few times, before I realized that there is some "next" button. It also isn't so pleasant to my eyes, but that could be just me. What bugs me the most, is - as mentioned in other comments - that there are only two difficulties. Then there is the thing with score - I really don't get the score system, like I have 20 something score, then I look aside for a moment and I have -5. It could be really good game, if it wasn't unfinished
