The lighting system, what is used for the dark circle around the player and how it expands when it is activated, and the collisions. I tried to make them better, like a transition between on and off when activating the bell pulse, a gradient between the light and darkness, and just better collisions. But, wasn't able to do those unfortunately. It wasn't like super difficult, but way more difficult than using Godot, as that just requires a node, and it's way more time consuming, which I was very limited to of course. Anyways thanks mate!
