This was a fun little game. Simple to play, and an easy game loop to build up your track.
I ran into an issue where the coaster stopped at a cross track and I could no longer interact with the grid. Everything else functioned, including hovering over the items on the grid displaying their details, though clicking "Launch Cart" did nothing. The cross track was the first I had placed and was not connected to any other tracks. There were other pieces adjacent to it.
