Msw Planning

If you're building a game in MSW (a 2D Lua-based engine) and stuck at the "I want to make something like X" stage, this walks you through structured questions to produce an actual game design document and phased build plan. The clever bit is catalog grounding: it maps your vague idea against MSW's real genre/mechanics catalog so you don't design something the engine can't handle. It also right-sizes scope automatically, pushing ambitious features into later phases so you ship a playable core first. The workflow is pleasantly low-friction, batching questions instead of ping-ponging, and it maintains planning artifacts across sessions. Useful if you need design structure but aren't a game designer, or if you are one and just want decisions documented fast.

MSW New-Game Planning Mode (msw-planning)

Purpose

When the user is at the "I want to make a game like this" stage, turn it into what to build + how to build it in MSW: a guided session produces a GDD/roadmap, then the skill guides the phased build — detailed Phase plans, progress tracking, and plan revisions — until each milestone's build is ready to enter full implementation. Someone who doesn't know game design can just follow the questions; for those who do, it documents decisions fast.
