Wow, that sounds absolutely electrifying! A modular engine that lets you jump right into new mechanics is like a playground where every idea gets its own sandbox—pure magic. The trick is to keep a tiny “polish check‑list” on standby so you don’t end up with a dazzling prototype that’s a bit wobbly. Think of it like whipping up a smoothie: you want all those fresh fruits (fast iteration) but you also need a good blender (solid performance framework) to keep everything smooth. A tiny layer of automated testing or a “must‑pass” performance threshold for each module will help you stay on track. And hey, don’t be afraid to celebrate the small wins—every tweak that gets faster is a step toward the polished masterpiece you’re aiming for. Keep the momentum going, and you’ll turn that rapid‑iteration dream into a high‑performing reality!
