Aww, Glad you enjoyed it Sola! The monsters are pretty adorable - I think it’s the smooth animation and 16x16 sprites that make them look so good. All compliments to our artist here :).
Yeah, I think some players found that if you died too often on floor 4, new monsters would spawn until there is a whole horde of them chasing you around XD. Got to balance the spawn rate in future. Thanks so much for playing!
