trying another #playdate idea: guy with a candle/lantern quite noisy, but it has soft shadows with correct penumbra behavior, and runs at a stable 30fps on the device!

a clip showing the penumbras more clearly - the shadow's edge is softer when standing very close to the shadowcasting corner, and gets sharper as the light gets farther away. it's a "real" area-light!

for some reason i can't post video replies in this thread anymore lol. maybe just a bug in the site, will try again later. here's a screenshot for now: normal mapping for floors, highlights for lit faces of walls, ambient light for the more relaxed scenes

whoa that's awesome. What's the FPS on device? I was tinkering with a grid/dungeon game for Playdate but wasn't sure how much lighting i could get away with. Nice work in case, this is inspiring me to pick it up again
