The lack of in game tutorial is definitly a fuck up on our part. Would have taken a few minutes and would have helped so many people understand the mechanics more clearly.
The combo system is such a clever way to encourage player to go for the most satisfying strategy in our game (devouring a lot of dudes). Another thing I've been thinking about is letting 15 - 20 seconds without holes at the end where the player needs to eat as many creatures to score bonus points.
Thanks you for the feedbacks!
