I'll get straight to the point. TLDR: Renders are exceptionally great, UI is unique. But the story is something else to be desired. (Update v0.02)
Overrall its descent, but feels like its mostly filler content than anything else.
Ussually when you introduce a mystery such as why your "love of your life" vanished without a trace, You will have to sprinkle in hints and ideas, to keep your audience engaged. Dev did absolutely nothing about this plot except mc getting shot, by who or what, WE HAVE NO IDEA. The plotline in this VN jumps around way too much. Infact this is a recurring thing that happens around this VN.
You get introduced to all this characters but its hard to even get to like any of them since they barely stay on screen for that long, and when they rarely do, you get these 2 manipulative (love interest im guessing?) characters that its hard to even like them. Like the spoiled little sister, who seems to have split personality disorder, teases you first then with a flip of the switch she gives you an ultimatum/blackmail to make you do whatever she wants, no questions.
The few kinda likeable characters such as the daughter who is barely on screen, only has basic conversations with the mc. The so called mother, who only shows up in flashbacks/dream.
Mc isnt likeable either, half of the time he's dreamin of the past, passed out.
other times he seems drugged up. HIs younger/older sister ( this part keeps changing thorughtout the game, i cant tell whos the young or older), has a thing for the mc, MC managed to escape from her lusting for atleast a decade from my understanding, and it only took him 1 day of him coming back to change his mind to be intimate for her.
Again, its hard to feel engaged to the story at all when there is nothing that keeps it pushing forward.
Still worth trying tho, might be good on the next coming updates.
