That's amazing, I've always wanted to have an AI companion help you out in battles. Well, that's if Chrono Trigger was harder than it actually was. The vanilla game is known to be quite easy, but I suppose that's better than having it be too brutally difficult and unbalanced. I'm curious about two things though:
1. You mentioned that if you attack the AI, it will turn off. Let's say you did that and decide that you wanted it on again. Would you just attack it again or will it stay turned off until the next battle? Which brings up yet another question: If you did turn the AI off in battle, by default, will it be on or off in the next battle? Hopefully, you can't accidentally destroy it by attacking it too much, haha!
2. Will there be other AI companion units available? I know that this might still be in the testing phase, but I'm wondering if such a thing would be possible? Maybe give the player a choice of which robot unit to purchase in the game and possibly the choice to exchange it at a booth if the player wants to try a different one. It would be interesting to choose from a list of all non-boss enemy robot units to have as a companion. It might make it more interesting to have more expensive and better units that a player could choose to save up Gold for and invest in it. Such units might also help the player win very difficult tournament style battles for better prizes that could otherwise be too hard without the additional help from an AI helper unit.
Nu might also make a nice temporary helper in a certain time period. Let's say, either when going to fight Azala through the Tyrano Lair or during the Ocean Palace stage. Or perhaps a knight (with a sprite like the prison guard enemy) could volunteer to come along with you to take on Magus at his castle or at least during the Zenan Bridge fight. If the player had this person in their party, it could just be said that he wasn't sucked through the time portal after defeating Magus. He might also be available to rejoin the party as well, but only when in the Middle Ages. For example, when taking on a side quest there such as the desert monsters for Fiona, Ozzie's Lair or The Giant's Claw island. Perhaps this knight could be stationed somewhere at the Guardia Castle or elsewhere in the city. It's just an idea. And as a last note, I would just like to thank you all again for working on such an amazing project. I hope that it all goes well, best of luck to all of you!
