Thank you for the kind words! I'm glad you enjoyed it.
A recipe book would've been great, but since there are multiple paths to many of the items, it would've taken quite a while to develop, especially in terms of UI. With more time, we definitely would have added something like that.
We made spears strong early on purpose, to make sure people have enough time to experiment once they discover them. Without spears you survive for around 4 minutes, with spears you get about 8 minutes and with multiple spears you already survive for quite a while. I think we missed the mark a little here, since while 4 minutes are relatively long, it feels very short due to the game being so overwhelming at first.
Thanks again for the feedback!
