Cool! I like your pixel-art a lot. My one suggestion is to have three buttons to switch instead of just one, so you can more quickly move between them without having to cycle through.
Thank you for your compliment. The art was based upon the Total Party Kill by AdventureIslands. Your suggestion might actually work, but I think I'll stick to this one button for now, this game was just a prototype after all and I don't have any plans to continue this.
