I'm glad you enjoyed it! For me it was the contrary, I started with Twine, gave up (curse you, audio problems) and moved to Quest.
Quest has its ups and downs: it is simple to write, add images and music, and there is a dedicated community of devs using the platform, but it is very easy to get lost while writing (unlike Twine), you can only install the application on Windows (hence the upper link I gave for the Mac users), and there is little assistance on the web when it comes to coding duo of it being overshadowed by other engines such as Twine, Unity, etc. (all which are good on their own).
In other words, in both engines you can make great games, but it takes time and effort to get used to each individually.
Ironically, the hardest parts of the progress of making this game was not writing it, but adding the music and publishing it, duo for the engine's limitations.
Don't feel guilty about having to gaze at a dictionary, or having to look at Wikipedia each 15 seconds to know what is the difference between a "Deinotherium" or a "Homotherium". Scientists are not the best when it comes to naming. :/
I'm interested on your idea of adding an encyclopedia in-game, of course in order to do that I would need to find how to code it, and again there is not much help on the web.
Still, thanks for putting time on my game and review. It really means to me, as cheesy as it sounds.
