Edit: Played the demo (676mb, I don't even) for about 20 minutes. Here are my thoughts.
I'm being incredibly harsh here as I get incredibly irritated when people charge money for a clearly unfinished game.
First off, let me comment on your "inspired by L.A. Noire" statement concerning the gameplay.
L.A. Noire did not make you analyse texboxes. They had a talented voice cast and complex facial animations to make it work.
The game doesn't even have voiceovers. How is that supposed to work as a game mechanic? And no, this may sound harsh,
but the writing isn't good enough to subtly hint at lies. The dialogues are
incredibly poor.
Grammar: Wagonload of spelling errors, typos (even in the trailer!) and sentences
often lack proper punctuation.
Writing: Regular intervals of needless cursing which makes the game not mature but rather immature. Characters are hard to take seriously because of the previously mentioned
cursing and it's also hard to tell them apart because they all sound the same. Without the face icons there is nothing to differentiate them. The pacing is also quite bad, cutscenes
jump all around, supposedly emotional scenes are rushed and the characters react in ridiculous fashion, making it impossible for the player to relate to it. This really is the worst
part of your game, considering the amount of dialogue you have.
The mapping is very bland, there is not much detail. The water texture looks like the sky, so I thought the game was set on a floating island. The general placement of regions
is also very bland. There is a school, which is connected by a long road to a your house. Said road also leads you into a forest where at the end is a beach, where the friend lives.
I don't know if it was fixed, but returning from the friend's house replaced the water tiles with random items... It wasn't pretty.
It's also confusing that in a game that is apparently set in the real world (Characters mention forensics club, navy, calling the police, DNA) has
medieval houses and clothing/armor. It's also silly that in such a scenario I have to take my hunting knife, kill wild wolves in a forest to savely get to another house.
I know this is a technical limitation, but the houses look terrible in 3d. It looks like the old Mario Kart on SNES.
Another thing: Cutscenes and the YouTube trailer have their XSplit watermark on it. This is rude, period. You want people to spend money on your game when you didn't even bother to get a
proper screen capture software? Are you serious?
I really recommend polishing the game for an adequate amount of time, right now it is nothing somebody should spend money on.
