For the game who already been published since 2020 it's still need more story especially if you are focusing on Visual Novel gameplay.
Rating from me overall 8/10
-good graphics
-good humour
-good story (but for 4 years of game you should put more story instead of graphics, after all it's visual novel)
For mobile user with low device:
1.5gb high graphics might be a little problematic, but if you Dare to go for it then have fun, because the game is good.
But still perhaps it will only end like ±3 hours.
Edit:
Tested with :
Android 13
InfinixSmart8 (working just fine)
128/8
