Thank you for your feedback.
For the art applying to everything, I agree, I didn't have time at all to remake a tileset, but I'll try to do it :).
As Waden already answered the babies don't grow up. I was thinking of a mechanic for that but that would make for a much bigger game! Maybe you could find new homes in the world and choose which baby would grow up and be the parent, and which step you want to have :).
SPOILER:
The secret passage is in fact used to get back all of the magic orbs you lose when you die, as you lose half of them everytime :). With this, the fact that the levels / enemies are too powerful is less relevant and you can just try to survive as long as possible to let them destroy everything by themselves and loot haha. That's a bit of a gameplay shortcut, I don't know if it should stay as is for later?
Anyway, thanks again!
