Eggselent(that's excellent)!
Very good, some lil' bastards are bothering you about how it's so unoriginal... I don't think it is at all! The only "unoriginal" part of it is the fact that the school design is pretty much the same... Although the hall moniter part and the way you navigate around the school are rather similar...
Anyways, great tribute to pico's school, if you morphed this, and pic's school together, you'd get a shit awesome game. You need the cool graphics and clickables from this one... Plus the extra puzzles, and just glue it onto Pico's school, microwave from 3 minutes to 8 hours and you would get a great game.
I liked the whole thing, I liked the lack of fighting and stuff, I really liked talking the teacher right before the principle. It was clever what you made the answer, I guessed it on my third try (w00t!)
The whole thing was great, but the part where you need to find the hallpass is alittle random, I started clicking on lockers at the begining (to check for medicinal herbs... Hohoho, bitch!). But none of them opened, I was just trying to click on the bubble of my guy talking, but I missed and hit the locker with the hall pass... Hopefully I didn't give away too much.
Though many people seem to find getting passed the fat kid hard, I found it to be amazingly easy. Only hard part was the hallpass really.
Anyways, cool game.
