Develop progress

So, that you know, I wanna tell you about development progress:

Progress:

Level design: 100%

UI design: 100%

Sounds design: 100%

Game mechanics: 90%

Artificial intelligence: 93%

Main menu, settings, loading screens and etc.: 93%

So, why development is dragged on?

So, in March - June I wrote final exams in my school (end nine classes and finally can go to the college!). I started development in February, but because prepared for exams I didn't work on game and in March demo was completed on 38-40%! I hope, I release demo in middle - end of August. I promise!
