OK, I used the Heal spell, and I teleported to a random spot on the floor. And got killed. I respawned. I got hurt, tried using heal again, teleported again, died even more gruesomely, and got a game over. WHAT?
In the second boss fight, it should be MUCH more obvious that you need to jump into its bombs. Also, it should be possible to jump over the explosions of said bombs.
Other than that, this is a fantastic game.
