Seriously?

I want SO BADLY to rate this 5 stars, but I keep experiencing glitches that occur after like 30 or so puzzles that completely hinders me from being able to continue or back out. I have to force close the app to resolve it and then manually navigate to the next puzzle. This was one of my favorite games about 5 or six years ago and I was so excited to have remembered the name to redownload it. I have tried deleting and reinstalling to no avail. I have only lost my progress. I am not even sure if anyone operates on this game anymore, but as I just paid for the Express version, I would really appreciate it if it worked.

Broke & P.Oed about Trainyard Express, v1.66
