Listening to Transistor's OST again while working, I'm still in love with this song : https://youtu.be/41tIUr_ex3g. I should play (and beat) again the game tonight, I really liked the combat system, though I didn't test all the combinations : since I'm a lazy ass, I just kept the deadliest ones and fought my way to the last boss.
Anyway, the soundtrack of this game is great, good job Mr Korb.
