What a frustrating disappointment.
I'll be very, very generous and give it 2 stars because the main girl is attractive (in spite of the short blue hair). Other than that I can't think of a single good thing to say about it.
It's lazy, too short to bother releasing, the characters are about as developed as a disposable spoon, the gameplay choices are there merely to trick the player into failure, the story is as shallow as it is brief (3 hours would be hard to reach even with all the endings).
My advice is don't waste your time downloading.
Gameplay:
There's basically no choice whatsoever in the actions you take. Selecting any but the one that gives a point leads to either an immediate game over, or a delayed abrupt game over toward the end, forcing you to start again.
Even using a walkthrough it required multiple attempts and was a struggle to reach the end (even skipping between choices). There's no point having choices if they aren't choices but merely a way to troll the player. And during one of those game over scenes it displayed an insulting message telling me "Use less ass in your choices. Your choices were ass.", which is funny given I was merely trying to discourage a character from being a struggling camwhore.
The 'minigames' were also annoying, glitchy and added absolutely nothing.
Graphics:
Eliza is attractive but the flat is so empty it looks like it's just been built. Is it really that hard to add a few props to it?!
There are constantly abrupt changes of location and the whole thing just feels rushed and lazy. The MC's underwear bulge is so large and unnatural it looks like he's got another character trying to escape from there.
Randomly included animations and transitions serve only to make progression feel unpredictable where you aren't sure if you should click or wait.
Perhaps this is a first attempt with Ren'Py?
Story:
I'll put this in a spoiler tag but it really doesn't have a story and I try avoid details, so feel free to read.
