A very fun and addicting experience (with a simple an intuitive yet challenging design). It was clear for me instantly how to play when the game loaded, and the immersion of being a traffic controller was quite well done. I like the interaction with the train, the clear diegetic UI for the "angryness" of car drivers. The sound effect of the incoming train was awesome. (It reminded me a bit of the game Train Conductor 2). The difficulty curve was well implemented, and it didn't start of too difficult. More maps (maybe an icy biome or grasslands) would be a cool upgrade. Do different colour cars have different waiting times?
