CONTACT

Short version: hello@amazingengine.co.jp. Long version below.

How to reach us

The fastest way to contact games.passed.jp is by email to hello@amazingengine.co.jp. The address is monitored by Amazing engine Co., Ltd. on business days (Monday–Friday, JST).

We typically respond within 2–5 business days. Faster for clear bug reports, slower for thoughtful feature ideas (we like to read those carefully before replying).

What to write about

🐛 Bug reports

Found a game that froze, crashed, scored incorrectly, or behaved unexpectedly? Please include:

• Which game (e.g., "Slime Crush", "Katana Slice")
• Browser and version (e.g., "Chrome 124 on macOS", "Safari iOS 17")
• What you did that triggered the bug (one short paragraph)
• What you expected vs. what actually happened
• A screenshot or screen recording if possible

The more concrete the report, the faster the fix. We aim to ship critical bug fixes within 48 hours of a verified report.

💡 Game ideas and feedback

If a game made your morning better — or worse — we want to know. We especially like hearing:

• Which game you replayed the most, and why
• Which game you bounced off of after one play, and what would have made you come back
• Mechanics you wish we'd add (e.g., "I want a level that's just rain")
• Themes or moods you'd love to see in a future game

We don't promise to build everything, but every suggestion gets read and discussed.

♿ Accessibility issues

If a game is unplayable for you due to color contrast, screen-reader incompatibility, motion sensitivity, or any other accessibility barrier — please tell us. Web games shouldn't gatekeep, and we'll prioritize fixes.

📰 Press and media inquiries

Journalists, podcasters, video creators, and bloggers covering indie games or the post-mobile-app web: we're happy to chat. Email us with what you're working on and we'll arrange a call or written Q&A. We can provide press-friendly screenshots and game GIFs on request.

🤝 Partnerships

Other indie studios, faceless YouTube/TikTok channels, ad networks, or platforms interested in collaboration — say hello. We're a small team but open to interesting conversations.

⚖️ Legal / privacy

For privacy requests (data access, deletion, GDPR rights), DMCA / copyright notices, or other legal matters — use the same email with a clear subject line ("Privacy request", "Copyright notice", etc.). See our Privacy Policy and Terms of Use.

What you won't get from us

• Marketing emails. We don't have an email list. If you write to us, we reply to your question and that's it.
• Account passwords. There are no user accounts on games.passed.jp, so we will never email you about a "compromised account" or ask you to reset a password. Anyone claiming otherwise is impersonating us — please report such emails to us.
• Payment requests. The site is free and there is no checkout. We will never invoice you.

Response times

We're a small team. We won't always reply within minutes, but we will reply. Thanks for being patient.
