Unforgiving was when the game was still alpha, now I changed the name and heavily updated the game.
The game is really challenging and i absolutely love that!!
you can add little graphical touch to the game by changing the lights from static image to light2d node and add child node to player called lightoccluder2d and dont forget to enable shadows in the lightoccluder and you also have to bolder it by that select-tool
this 3mins video might help
he did what i mean at min 2:18 but instead of player be the light source the player will be the occluder
have a nice day !😀
