The point of the game is to:
A) Have fun
B) Trigger misconceptions commonly encountered by physics novices
C) Be a fun homework that teachers can then use as a tool to address student's misconceptions
There are enough educational "games" out there that make you answer questions, apply formulas, and otherwise fail to exploit video games learning potential by trying to force a school's curriculum in preexisting game mechanics. Mecanika takes a different approach: it is a game about solving tricky physics puzzles, which hopefully will change how you think about physics, thus laying out the foundations for a proper education in the classroom.
Here are some screenies:
Mecanika will hit the interwebs on Winter 2011. In the meantime I will post my progress here.
