Not Long, but fun
It doesn’t take long, I think it took me half an hour tops to get 1st rating on all 8 missions, but it was so much fun trying to get there by making different decisions, and oddly satisfying when I did.
I don’t think the game developers have English as a first language, so there are a few spelling mistakes and I recall reading one sentence that made very little sense to me, but I still understood what choices I had etc.
Basically, for a free game, this was a lot of fun!
