I haven't messed with a lot of lighting in 2d. You couldn't use the default lighting because of it's limitations? I had fun playing the game, that's for sure. The difficulty was average I would say. Depending on what room you were in sometimes it was too easy because the AI awareness was set to too small of a radius. I would experiment more with that maybe, but it's truly personal preference there :)
Yeah I was trying to get the dedicated "2D Light" node provided by Godot to work in a 3/4 perspective, as is the final product. However it looks like it's meant for directly overhead top-down views. So, I had to wing it by using another type of 2D texture light and overlaying that to get the effect I was looking for (with the light "shining through" objects). If you or anyone's used Godot and has tips for that I'm all ears haha.
Glad to hear the fun was there, but also that it was too easy sometimes. The difficulty was a concern of mine going into the final stretch as I was running out of time to fine-tune, so it definitely could use some improvement there. Same with level layouts to compensate. Thanks for that feedback :)
