Nice game! I noticed when I first started playing my health kept ticking down but after grabbing some potions it stopped and stayed steady after that. It seemed to start ticking down again on each level. I thought maybe since I was in the poison fields it was supposed to tick down so I'm not sure. It took me a while to find all of the enemies on the first level, at the end I was wandering around for a while before I realized that there was more space in many of the areas that I had already explored but I needed to walk on the edges to find it. I also noticed that my life started going up after I defeated an enemy, probably intended.
I made it to Pustorak and defeated 3 bosses before being defeated by the 4th level boss. Once I died it did a message saying the final boss was ready again before the message went away and I could restart the game.
Overall awesome, I liked that there are attack sounds and music, it's always hard to get that extra polish in but it really makes the game feel more alive.
