This is a bit of a hard one to rate, since Extra as a game is so... Experimental? Weird? It tries a lot of interesting and different things to try and convey the sort of feeling you'd get with the back-and-forth of Servant battles in the original VN. Thing is, most of the time, it sucks. The core gameplay loop is essentially glorified rock-paper-scissors, where guessing wrong one too many times means an easy and instant game over. Playing this is like pulling teeth, and it practically DEMANDS the use of savestates, save scumming, or just straight cheats.

All that said, the game is utterly oozing with soul and love for the characters, such that it's almost possible to forgive the gameplay. Definitely worth checking out for that alone, if you can get past the rough exterior.
