Thanks for the reviews!
@ratking:
They do throw some apple cores / bones after eating, but it doesn't happen right away, and there is no other animation, so not very good feedback.
And I absolutely agree about your own trolls being too hard to spot. There is a faint blue aura on them, and they generate mana stars, but it's not easy enough to connect to individual trolls. We were thinking of making a post-compo version with various improvements, one being having distinctive hats for your own trolls ;)
@Gidaio:
Point taken, tooltips and an intro screen outlining the objective at the start might be other good improvement ideas.
We also want to add a bit more of a level/wave progression, now it's maybe a bit too sandboxy and not challenging enough once you manage to grow your tribe a bit.
