We use the platformer behavior for the character so when S is pressed it's used to drop from platform, although since we don't have alot of assets we use it for the ground as well but we add invisible floor too so the player doesn't fall off the screen hence that you fall a bit low when pressing S. And sorry for the fire orbs hahaha, it slips my mind to add the warning indicator for that, I'll keep that in mind in the future. Also the player can still died after collecting all of the orb before the boss truly disappear is intentional, so the player must keep their guard up till the end hahaha.
Thank you for playing our game, I'm glad you like it!
