Nice graphics! I included it in my compilation video series of all the games entered in the GameMaker Studio 2 Beta Jam #2, if you'd like to take a look :)

An interesting one. I like the idea of the one large "journey" the player undertakes rather than a sequence of levels. I unfortunately failed, only bringing 3 followers to the very end. I feel like I was often waiting for followers to catch up with me, although their frantic behaviour when meeting an enemy was cool.

It would perhaps help if there was a way to predict the spawners more readily, as enemies can very suddenly spawn on top of you before you are able to react.

Cool submission, good job!
