I got bored half an hour into it. Have yet to resume playing it.
Earlier this week I resumed the game only to find out that my progress from earlier was not saved. Didn't think much of it, started from the beginning again since I didn't get that far. So I play a while and then quit the game to do some other stuff. I get back to the game later same day, only to discover my progress wasn't saved this time either.
Fed up, I search the tubes for answers. Read that this is a common problem caused by developer decision to save only at beginning of each mission. Meaning checkpoints don't work as proper saves if you quit the game.
I promptly uninstalled the game and moved it to Steam's "Trash" category. At least the game was cheap, but I still didn't get my money's worth out of it.
