The game crashed and since I hadn't saved for a few minutes, I restarted from the beginning.
I played my second run until the timer ran out. When it asked me to save, I did so and the New Game+ option appeared. However, when I try to start a NG+, it just takes me to a black map with the countdown at 00:00 and a game over screen shortly after that...so I guess my save file is unusable now.
Since I lost a lot of progress, I probably won't play any further, but other than that, I enjoyed Rxcovery and would definitely play a sequel!
