It is very interesting how many people find similarities to Inscryption, even though it wasn't a main inspiration for the game. It is a big compliment and we're very happy to hear that you enjoyed the game :)
Thanks for the feedback! Unfortunately, since the shaders need to compile I don't think there's any way to speed up the process, maybe we can put a loading bar for the first launch of the game. we will look into it, maybe there's a way :)
Cheers!
