The three endings are:
1-Build a dungeon( the path after breaking the magic seal)
2-Destroy the outpost commander(I forgot the tile name)
3-Evolve( the path after growing fangs)
Yes there are two:
1- A route that you can beat the game before the second opponent
2-You can get enough power in the upgrades after the rune of knowledge(I am not sure about this last one, I haven’t used it in a while)
There are still a few glitches in-game, like when you delete your own save, the skill tree doesnt reset(it works some times), and whenever you destroy something with splash it gives nothing
