Create the training game

There is a simple and trash implementation of game right now. This needs reworked entirely for an actual game people will enjoy either alone or with someone (possibly)

Start by reviewing the current game implementation and its existing behavior. Clarify whether the goal includes solo play, multiplayer, or both, then define what an enjoyable training game should contain and how completion will be evaluated. The issue does not identify files, tests, or a specific entry point.
