It looks pretty solid, plays well. It is clearly representing the theme, but I feel it is a bit limited. Graphic wise it is alright and the sound suits the game's flow. Nice.
When I have time to play it again, I will make some notes on the specific things that ....made me lose interest....Be sure, I have played plenty of games today, so perhaps I am just 'play tired'....So on the second playthrough it might seem better :D
