I love these two mockups, great job. Looks like a fun game too.

Very awesome. 

He's a real bad, kid, sitting at the back of the room.

Well I couldn't get to the next level Teacher threw me out!
Clock could / should go to the right top.
The right hand side seems to be empty which could
have some of the rest of the items as well.
What will I do with the beetle .....
I like it!

Whats the dithering on the desk for?

Something kinda bothers me. The room is top down, while the sprites seem like a side view, kind of like this.

Still nice job.

man this looks like some serious fun! i wish this were a real game ...

ice idea and nice picture - i dont like the white outline too much and the interface is so busy it allmost messes me up.
