Have an option for english maybe? Unless you can't speak the language.. theirs many version of this kind of game out their.. this is pretty decent, add some music. 2/5.
I liked the basic concept of the game... a fast paced tower defense. Althought the sound effects were a bit annoying.. it did provide me with a temporary joyful experience. The instructions need to be a bit more clear and add some music. 2/5.
Its not meant to be original the developer made this game as another variation with a different theme. Add some relaxing music and sound effects. This would definately be a good casual game. Although, I'm not really much of a fan of reversi. Good job!
