Hi! Thanks for the comment! We're glad you liked it!
We didn't feel like doing something mechanically sophisticated as this is what I focus on in my other projects all the time. If we ever decide on making a longer game about crows and their journey, I'm sure a similar risk/reward system will be present in some way.
We were curious how much do we need to hint at the ending of the game, but so far everyone managed to "beat it." So I guess we'll leave it the way it is. With a little mystery. Thanks for your suggestions though!
