TL;DR : Good art ruined by bugs (or weird logic) and bad translation.
Art: 5/5
Girls are cute and art is nice.
Gameplay:
During paused time you have to watch out so the clock doesnt run out of time. Time slowly continues as you play and also every single action takes certain amount of time. At start you can only handle small amount of paused time, but as you "level up" you can handle more ecchi actions. Interesting mechanics.
Unfortunately game suffers from bugs or author used really weird logic and didnt bother to explain to players. After you bring girl to orgasm you no longer have to hide after time stop ends. It would make sense for horny girl alone in classroom, but what about a female in a room full of teachers??
Also certain bugs completely stopped me from progressing and I had to replay from older save. Example: girl completely disappeared and never came back.
Another bug at your house will stop you from ordering books to improve your ecchi actions. Game doesnt allow you to buy 1 book, it will show you amount of books you want to buy (1-100) and despite the number you choose, it will promt you to buy 40 books at once for RIDICULOUS amount of money.
Also progress trough game is very unclear. I had no idea how to continue.
Translation: 2/5
Its typical machine translation, but at least its on the level where you should be able to understand what are you supposed to do. Unfortunately text sometimes runs out of screen (it fails to continue at new line).
Overall game has some potential, but at this point its really frustrating to play. I didnt manage to "finish" the game (see all content). I dont know whether I failed due to a bug or whether I missed yet another hidden thing by author.
