> go言語でテトリスのゲームを作成して

⏺ I'll create a Tetris game in Go for you. Let me set up the project structure and implement the game step by step.

⏺ Bash(mkdir -p src)…
  ⎿  (No content)

⏺ I'll implement a simple Tetris game with the following files:
  - Main game file
  - Tetromino definitions
  - Game logic
  - Rendering

  Let me create these files:

⏺ Write(file_path: src/main.go)…
  ⎿ Wrote 45 lines to src/main.go
     package main
     import (
       "fmt"
       "time"
       "github.com/nsf/termbox-go"
     )
     func main() {
     … +35 lines (ctrl+r to expand)

⏺ Write(file_path: src/tetromino.go)…
  ⎿ Wrote 254 lines to src/tetromino.go
     package main
     // Tetromino shapes
     const (
       I = iota
       J
       L
       O

⏺ Bash(cd /Users/xxxx/xxxx/xxx/ && go mod tidy)…
  ⎿  Error: (eval):1: command not found: go

⏺ It seems Go is not installed or not available in the current environment. Let me create a simple Makefile to help you build the project when Go is available:

⏺ Write(file_path: Makefile)…
  ⎿ Wrote 11 lines to Makefile
     .PHONY: build run clean
     build:
       go mod tidy
       go build -o tetris ./src
     run: build
       ./tetris
     clean:
