Modulus Feedback & Suggestions

🛠️ Modulus Community Feedback Hub

Welcome to the Modulus Feedback Hub, your space to share ideas, offer suggestions, and help shape the future of the game.

Whether you're diving into the public demo or testing our in-development build, we want to hear from you.

✅ What to Do:

  1. Search first – If your suggestion or issue already exists, upvote and comment instead of making a new post.
  2. Be specific – Clear, focused feedback is more helpful. Add examples if you can.
  3. Stay constructive – Honest feedback is essential, but respectful communication helps everyone.
  4. Tag your post – All submissions must include a topic tag (e.g. UX/UI, Balancing, Bugs, Suggestions).
  5. Playtesters only: If you're leaving feedback based on the Early Access playtest build, please also add the playtester tag so we can track it separately.

🗂️ How This Works:

  1. Similar posts will be grouped or merged to keep things tidy.
  2. The most upvoted suggestions rise to the top, so show support for the ideas you like!
  3. Our dev team may occasionally add tags like Under ReviewPlanned, or Completed with responses.

💬 Questions?

Head over to our Discord server for help or more info.

Thanks for helping us shape Modulus, we can’t wait to hear your thoughts.
