A small platformer scaffold that exercises every recent language
feature in one place:
- \`struct Player { ... }\` with u8 and bool fields
- \`enum Direction { Up, Down, Left, Right }\`
- \`enum AnimFrame { Idle, Run1, Run2 }\`
- \`for i in 0..4 { ... }\` looping over a fixed-size array
- Struct field assignment and reads
- Enum variant assignment
Compiles through the default IR codegen and links cleanly.
