Ooh, thanks for all the ideas (and for playing) putney!
Easier solution could be to have a visual indicator on the bombs themselves to show the blast radius, I should have thought of that!
I found myself putting the spare potions in the same spot myself!
I love the tall grass idea, though in the current game it would get cleared out *very* quickly unless it also grew back
Placeable walls that the enemies attack would be good, right now the enemies are a little too dumb for that! The skeleton's bodies serve a similar purpose.
I actually have a sprite for an ice slime that I ended up not using, it would have left a trail that slows down the enemies.
