I'm really sorry to hear that. I would have liked to do some optimizations, as I use a lot of lights and post-process effects combined with lumen, but I didn't quite get there (as you could see). After the jam rating period is over I will update the game to improve some aspects, including as much optimization as I can (I'm thinking about having Lumen as an option).
I apologize for handing you a frustrating experience, thank you very much for taking the time to try it!
