Aside from some technical issues excusible in beta, the game - the atmosphere, the graphics, music - all is great
A plot is simple. Yes, but it's pretty beautifully written with a bunch of alive characters and dozens of good jokes. A music is theme is short a bit. But it is beautiful. And it isn't annoying (unless you are stuck in the game menu for half an hour). And the best part that many "A-projets" are missing today. Very good skill system (no useless or stupid skills, no "kill-em-alls" that will lead you to the end of game without thinking. Very very well designed levels with different tactics in mind. Some of them can be beaten only with a good idea. Every level including the ones full of monsters, is a good puzzle. The game is really hard on the "Medium" difficulty. Some levels take hour to find a solution after replaying it three or four times... And I can't avoid appending that. As a programmer myself I have to say that the game engine is brilliant. It's fast, has a good graphics and runs extremelt smooth. If only the "big" RPGs was designed that thoroughly...
