DragonRuby Game Toolkit: Lessons Learned
summary
Engine celebrates five years, ships a cross‑platform runtime for iOS Android Nintendo Switch Steam, and hosts 400+ games on itch.io plus 150 sample apps ordered by difficulty. Performance claims include 60 FPS with 5K many-to-many collisions and rendering 20,000 moving sprites; binary size is 6.8MB universal binary versus ~60MB for the alternate build. Design choices emphasize hot‑reload, a built‑in REPL, mRuby zero‑dependency runtime, progressive disclosure of complexity, hash‑responsive accessors and module-based APIs to ease beginner-to-advanced transitions.
