A good concept, but with some really frustrating gameplay and bugs (in version 1.0). To name a few: 

- Having to select "yes" to givin Lelah the worm sample multiple times to progress the game, I think 7-9 times

- The table in the final area blocking the snail statue

- The shell needed for the snail shrine disappearing upon reloading my save

- The mechanics (such as being able to put the book in your bag) not being clear
