Hey fellow jammer! I enjoyed playing the game.... I LOVE TRAINS (if you haven't figured that out by my username). I like how simple the mechanics are and how complex the puzzle is. One big problem I encountered was impossible levels. Once I hit the fifth or sixth level, the game starts giving me impossible levels, as there are not enough passengers in the stations at all to complete the level, even with multiple nice view tickets. That ruined the experience quite a bit for me as the game became very RNG-heavy.
Despite that, I still love this game, and it is rather impressive how you piece it together in 4 days! This game looks almost like a complete game instead of a game jam game... GGs!
