Too controversial to really evaluate...
Ok, to cut very short - i believe this game is insane mix of good, of bad, of hardcore and WTF.
Lest start with Good : Pixelated picture, level design, atmosphere, music - is all good. Very good at most parts. I like exploring lonely depths, i like watching seaweed grow, i like chasing fish. In term of atmosphere this game have one hell amount of it, and instantly reminds of Aquaria.
Bad: Overall controls is clunky, sometimes you have to switch weapons fast or make fast moves and its plainly hard to execute. Weapons are weak. It was probably designed this way for more challenge, but range, accuracy, speed is all bad.
Hardcore: Boss fights. In general, they INSANE and insanely, unfairly hard. Its takes just several hist for most to kill you while you have to shoot million time to really deal damage, and some can heal themself. Usual problem is bounce to death effect or "crash to death". Bosses usually very fast, hardly predictable, emits various obstruction and so on. And several of them is ultra easy - just to tease you. It takes 5-20 tries to kill one!
With mostly harmless and peaceful nature around to explore this difference is little too much. Also, most boss fights occurs in dark places, which doesnt help.
Now, for WTF. Its plot, mostly. Well, its overall fine, but quickly starts to feel as way too cheesy Sci-fi. Even casting environmental questions aside its full of holes. And worst part - ending. Yes, there is one - ultimate answer for your quest of answers. After final encounter plot goes bananas - in scripted event your character do some absolutely pointless and meaningless things and after that its suggested that "all done, time to die peacefully". This part wast complete leftdown for me. Usually player is given some kind of choice with different endings, but not this time. Ending is just BAD.
Conclusion. Its overall fine game. Nice underwater stuff with challenging battles. But i wish it was better thoughtful..
