Other projects have take up my time, but as you can see from previous dev logs, I continue to add improvements.
I also have some short-term plans to extend the game:

• Add a few different backgrounds for different routes
•  Possibly add a rail map as well
• Display your score at the beginning (if you use the save game feature)

The (background) music will probably stay as it is. The developers on GB Studio (the tool I use to make the game) have made some changes to how the sounds & music works, and while the built-in tools will be handy for working on future games, it also broke how my sound effects worked. Which is why I pushed several bugfix updates in short succession. So I'm going to leave the audio as it is, now that it works again.

Meanwhile, if you want to play something else, I released a new game a couple of weeks ago called The Empire of Dreams.
Check that out if you would like to try an exploration/point-and-click game. It's inspired by the paintings of surrealist René Magritte and takes you on a trip through dreamscapes full of iconic imagery and some hidden objects.
