Liked the concept of a group sacrificing humans to send them to heaven to find God. I did get a bit lost in terms of where to go. I kept cycling from one location to the next and then suddenly the game crashed the third time I tried to visit the `???` area.
Choices could use some work. I found the game kept asking me if I wanted to proceed without giving me new information. For example, I choose to go to the Archaeology Site. Once there the game almost immediately asks if I want to look around or leave. I chose to go there already so presumably I want to look around as I haven't been given any new information. If the player's being given an option to rescind a decision, you need to give them some doubt or introduce a cost to proceeding. Otherwise you're just asking the same question twice in a row.
Otherwise, I liked a lot of the background art and some of the character designs like the skeleton deer were pretty cool. Would be interested in a fleshed out version of this world where sacrifices are sent to heaven to find God.
Good luck!
