It's a pretty cool game with stealth and PS2-like graphic mixed into the game. Of course, there are something that sometimes infuriates the player such as how inobvious it was for the transition and all.

The transition between stage? The huge crystal at the end of the stage that you're supposed to go to? It's a bit confusing when I encountered over it and I couldn't figure out how to get to the next stage. (I think I had to click something or I was not going to the right place?)
No problem! Happy to give feedback!
