Golf Game — Functional Golf (Ruby + Gosu)

Problem

Model golf mechanics and surfaces with pure functions; keep rendering/IO at the edges.

Approach

• Immutable State struct + reducer(step): state → state; inputs/events are pure.
• Tile system from external files (levels.txt, tile_traits.txt); surfaces change bounce/roll physics.
• Configurable surface physics allowing custom bounce and roll profiles per tile type.
• Resolution-aware rendering; Wind and obstacle effects parameterised for easy level designer tuning.

Outcomes

• Level designers can create and test new maps without modifying code.
• End to end game experience with configurable physics and levels.
