How AI is used
AI was used in the creation of this game, and its important to be clear about this as a solo dev. But every aspect of the game that AI was used as a helper/producer was reviewed by me, and thoroughly edited, tested, reworked, perfected and placed with intention by me. AI was used to generate assets, code and tools to help me be able to finish this game working as a solo dev.
The developer's own words, from Steam.
About NanoPets
Your desktop has company.
NanoPets is a creature collector that lives on your desktop. Your pets hang out while you work, study, or watch something. In between, meet new companions, decorate their Home, and put together a team for expeditions with automatic battles, pvp with your enemies, and coop with your friends in this mmo-like experience.
Throw them a toy and take a moment to see what happens.
There's always room for one more
Perform rituals to meet new pets, discover special appearances, and grow your collection. Keep your favorites on your desktop or find a place for them on your team.
A Home that feels like yours
Collect furniture, decorate your Home, and watch your pets settle in. Craft items to support your expeditions and choose outfits for your character.
Your team is ready. The sofa is still in the wrong place.
Build the team. Let them handle the fight.
Pick your pets, combine skills and equipment, and send your squad to face enemies and bosses. Battles play out automatically, so your part is preparing the team and trying different combinations.
Watch the expedition unfold or let the team carry on while you do something else. Then use what you've earned to get ready for the next one.
Bring some company
In Grand Adventures, join other players for cooperative challenges. Get a group together and see how you do as a team.
Put your team to the test
Challenge other players' teams in ranked PvP. Battles are asynchronous: players prepare their lineups, then the teams face off in automatic combat. See what worked and adjust your team for the next battle.
Say hello. Make a trade.
Chat, make friends, and trade items with other players. You can also browse the Auction House when you're looking for something in particular.
