Over all, the game was pretty good. Maybe the story wasn't anything new but the atmosphere worked well. It kept me entretained for quite a long time. I liked the future and present mechanic.
Sadly, there are some flaws. Most of the objects are useless and it's not better when some items that didn't have anything before suddendly have something on the next floor. Some of the deductions the character made we're a bit of a stretch. The use of that many doors in a 2D game made me feel like I was in a maze. Grammar wasn't such a big problem since it was kind of funny, but it removes me from the game. the cliff hanger doesn't feel right. It's not like a continuation is needed.
You just need to work harder and you'll have a great game.
