From a tutorial to a playable loop

A tutorial teaches one technique; a game combines techniques into a complete loop. Connect input to movement, movement to a rule and the rule to feedback before adding another feature.

Use a checklist with a start state, one challenge, a success or failure result and a restart. That structure exposes missing transitions that a single animation or rendering demo can hide.

Build the smallest version with simple shapes. Once a full round works, replace placeholders with purposeful visuals and sound. Keep the rules readable during that change so polish does not conceal a logic error.
