Probably because it have lots of buggs like:
1- When trying to serve customers the game crashes unless its changed to Spanish language before hand.
2- After every work time, the date with the teacher starts and sudennly you timetravel to Tuesday.
3- When working, every two weeks the 4 tables get with one less available. The table is there but nothing happens when you place the bell on it and atm i cant serve customers cus the tables are there but not working.
4- The phone works only in the locker rooms left from the pool and nowhere else.
5- When i use PC to check the quests for characters the quest page turns to FB page which is unusable so far.
6- The comand buttons are too spread like for example you can go out only from your bedroom and nowhere else, you can use phone only in lockers room, the quests are available only on pc while FB works only on phone(for calls), you cant skip school or at least i cant do it.
7- When i open "Map" and ckick on schoool nothing happens before the other location images load.
8- When im in mids of dialogue and click somewhere randomly on the left side of screen, the game rolls back to previous few interactions before hand.
Those are all bugs and things i experience while playing the game. I hope that you will fix them and in the future test a "release" for bugs before releasing it. Good Luck with development!
