Awesome game! Good job really.
I have only played the Heist mission so far, but I haven't finished it:
I managed to solve the first part with the hostages, but later one, near the boat, I rewinded time too much and "broke" my initial solving of the "heist" situation. That was quite demotivating... Could it be possible to add a "saving" mechanism, either manual or automated at some given checkpoints?
