Cool game! I thought I was going to get an easy win on my second run, but Jörmungandr was way more powerful than I had anticipated (I'm actually not sure if I died to him or if I lost to the Ragnarok clock). Eventually beat the game though!
I'd like to see more descriptions on the items, since it's unclear which will be better than the others (not that it matters much, since you want to be shapeshifted as much as possible)
Oh yeah, and I couldn't tell why it would be advantageous to increase your Serpent form tail.
