Lower the barrier by a little. Keep the craft intact.
An idea can be clear in your head and still feel far from a playable game. The first obstacle might be knowing which object to touch, which script to read, or how to tell whether a change worked. A helpful tool should make those steps legible.
That is Alder's positioning: help creators reach the work, then stay close enough to understand it. We are not trying to replace developers. Experienced developers deserve tools that show their work plainly and give them final say. New creators deserve a path in that does not pretend there is no craft to learn.
Help should leave more agency with the maker, not less.
