I like the idea,
its fun do redirect the train and watch the consequences
Just the switching feels a bit unresposive,
Sometimes I need to click more often and sometimes it triggers but I didn't notice right away
becaues the lever is a bit slow
Maybe have a little sound feedback or a quick visual indication
Sound is great, background music seems to get a bit annoying after some time
some variety might help, or a mute bg music butten
All in all a fun little game and an interresting take on the jam
