I struggled with thinking of something to go with this theme. I decided to make a game loosely based on an Adventure Time episode called Dungeon Train.

You are stuck in an infinite loop traveling through train carriages. Each time you progress forwards, the enemies get a little bit harder. Sadly I didn’t get a chance to balance the game, so it starts off incredibly easy, and then several carriages later it gets impossibly hard!

I’ve got lots of great feedback, and I’m going to do one post LDJam update to reflect all the ideas and inspiration I’ve got from the comments.

All in all, I’ve really enjoyed this Ludum Dare. Already looking forward to the next one :D
