Some of the boulder shots were just to make you feel secure and safe, after which usually comes an extremely fast one to try and catch you off guard. I don't know if you refer to that or if it even worked, but thank you for your feedback regarding the level design.
Thank you for the tip regarding the particles, I guess I could just add some kind of load screen where I first load all the particles. I will definitely try it out. I hope it didn't interrupt your experience too much!
Thank you very much for the feedback and tips. And most importantly: Thank you for playing :D
