I think that could be a good idea to allow the train to leave after you've had time to assess the situation, thanks for the suggestion. I know some people have enjoyed the speed of the game but others have found it too fast. Although it's never going to be for everyone, I would like to make it as accessible as possible and I appreciate the constructive feedback.

Update: I have made a minor tweak to the game. You now have unlimited time before the train arrives when starting a new game. The train will not leave until you start switching the tiles. It will still leave automatically when completing multiple levels in succession but this will reset after you get a game over. I think that this should maintain the challenge for the people who want it but hopefully make it more accessible to other players who have found the game too difficult.

Thanks a lot, this is my first game and it's really encouraging to get such positive feedback. I would love to make more games but it would be a waste of time unless people were going to enjoy them.

Thanks for the feedback.

Have you tried it on slow speed? It slows the train down to half speed, which should give you a lot more time to figure things out.

It's hard to balance the speed as I want to give some sense of urgency but obviously it can't be too fast or it becomes impossible. I added the slow speed so you can take time if you need to, and you also have unlimited retries. However, the speed might still need tweaking and I would consider adding more time if most people are finding it insufficient.

Good to hear that you had fun. I wanted it to be challenging but hopefully not too frustrating.
