What you give up either way

  • Polished art, animations and sound assets that a commercial studio would provide
  • Cross-platform publishing polish (stores, wrappers, automatic builds)
  • Any proprietary analytics, AB testing, or monetization integrations
  • Large-scale QA, device compatibility testing, and marketing

An open-source project doing the core job proves a replacement is possible. It does not prove it matches Blastrunner, and it does not prove anyone has run it for a month. How we decide.
