The idea of procedurally generating these monsters is interesting. Graphics are faithful to the era and setting.
On my first run, I got Neothodon. Only one of its abilities does any damage, and not very much--it's very hard to win a battle with this as your first monster.
Not sure if there was sound; I didn't get any when I played.
Also, when I brought up "Party" in the menu the game crashed for me.
