Prototype a game with AI, then plan your Steam release

Build Ashlight Courier, a desktop game prototype featuring keyboard-controlled isometric courier adventure through a volcanic village. Focus on desktop keyboard and mouse controls, a bounded playable slice, and explicit build validation. Define movement and interaction controls, readable feedback, a clear success condition, an understandable failure state, and a restart button. Begin with one complete playable scene and avoid unnecessary menus or paid purchases. Include a short controls explanation and a pause option. Use original characters, environments, and audio placeholders; do not copy protected brands. Test the core loop, collisions, scoring where relevant, and the ending before expanding the scope. Use WASD to move and E to interact with village residents; collect three parcels and deliver each to the right house while avoiding periodic lava vents. Treat this as a desktop prototype for a possible future Steam release, not a Steam-uploaded or certified build. Do not invent Steamworks integration or claim platform export is already verified.
