Sorry you encountered that bug! We had very limited time for testing and didn't catch it. We also didn't have quite enough time to animate the enemies, although I agree it would have added a lot. The final boss is supposed to have a random chance of dropping a health potion in front of you every time you hit him, but this may make it difficult to fight him if you didn't have that much health to begin with when you got there. Again, we had limited time for testing. I think I only played through the submitted project once, and even then I think I got to the boss by just jumping over all the other enemies.
