How did Astra change the scope or ambition of what you built?

Maker

Astra helped turn a small, two-battle spirit-card prototype into a complete browser game. Using Astra in Codex, I expanded the design into a three-chapter, 18-stage campaign with 30 collectible spirits and 90 forms, branching evolution, team building, and local save recovery. The scope also grew to include invite-link battles with a friend and English/Chinese interfaces. Astra helped across implementation, debugging, and validation; the released version passed 173 automated tests, alongside real browser playthroughs. The result is a playable game people can explore immediately. Astra's role was in building the product: battles use deterministic rules, and the public game does not make runtime AI calls. Creature artwork was pre-generated separately with Image Gen.

Hi Product Hunt! I'm sharing KINBOUND, a browser game built around three spirit companions and the choices you make with them. In the solo campaign, you explore three chapters and 18 encounters, collect 30 spirits, and choose between two evolution paths for each. Enemies reveal their next action, so your turn is about planning: spend energy on a tactic, switch in a reserve, or commit to an attack. Evolution changes a spirit's strengths and tradeoffs, and you can change unlocked paths at camp. The game is free to play and needs no account. It includes English and Chinese, browser autosaves with file import/export, and a separate invite-link mode for battles with a friend. The friend mode currently uses six starting spirits; the larger collection belongs to the solo campaign. The artwork is pre-generated with Image Gen. Battles use fixed rules, and the public version doesn't call an AI model while you play. Start with the campaign link; the language switch is in the top bar. I'd love to hear which team you chose, where a rule felt unclear, and which evolution tradeoff was hardest to decide.

From 2 battles to 90 spirit forms: building KINBOUND with GPT-6 Astra

Hi Product Hunt! I'm Kevin, the maker of KINBOUND.

I started with a small, two-battle spirit-card prototype. Using GPT-6 Astra through Codex, I expanded it into a browser adventure with three chapters, 18 stages, 30 collectible spirits and 90 forms.

The core idea: see the enemy's next move, then build your answer. Bring a team of three, manage energy, play tactic cards and switch your front line. Each spirit has two evolution branches with different strengths and tradeoffs.
