I can't think of a better example of so much effort put for a such lame experience.
The effort put in it and the artstyle are kind of unique, and given the fact the really small studio you are, it is worth mentioning it.
but the gameplay experience is just bad.
Like real BAD, the navigation is boring, every rock tile end up repeating itself. The sound and particle effects begins as a real pleasure with headphones on, but like rock tiles, they end up redbarelled.
And last but not least, the gimmick on which this game relies on, the bosses, they certainly lack some animation fluidity, but that's not the major issue here. the combat with the 3 bosses I've defeated, was kind of the same repeated three times, their different attacks feel kind of the same without feeling nothing (not even bad for them) Why just 3 bosses ? because of "The Tranquil" as you call him, that's reallllly poor game design here. nothing in it's pattern seems noticeable, like the fact you can cut up his tentacles (which respawn automatically after), the most awful thing comes from the submarine we're controlling, which is barely visible amongst all the elements on the screen, after dying repeatedly against this giant squid the game end up crashing (like 2 or 3 times earlier in my playthrough)
The conclusion of my thoughts on this game are quite the opposite of your latest game, Post Void.
I think your ambition on this project gone too far at a point that the game feels unplayable and redundant. It's the very opposite of Post Void, where you weren't afraid to propose a very short and condensed experience, when we play at it we do the same actions but every time a little different, and the jewel that's Post Void costs half the price of this scam !
yes I call the Aquatic Adventure of the Last Human (and besides Life Aquatic remains one of my favorite films) a SCAM, continuing to sell it for money, without knowing if it will work or not, is called, in fact, scamming people.
and that's not very pleasant for such unique and good working guys like you are.
Do Something yo !
