This is a fun concept. I imagine enemies will be affected differently and there will be different types of surfaces.

I've made the slime temporarily stop an enemy as planned, and been testing some other ideas for the slime too, I have been thinking that players might not need to use the stopping power of the slime and might be boring and just retreat, so I've only tackled these, but will definitely look at doing something with different surfaces could be fun
