The developer of this game is pretty impressively good programmer. He worked for a very long time on this game,as far as i know parallel with creating great deal of custom tech for it. Impressive that he didn't give up. On the other hand, this game has a pretty cool concept, but the game design part (adequate difficulty curve, tutorial, progression, level design) of it is lacking. It's quite common for movement games to be easy to pick up and hard to master, this one though is hard to pick up and even harder to master. Often times it even felt like me completing a level was more of a luck (AI decided to act irrationally) rather than my own skill. That's not satisfying game design.
