怎样用VB编写打字小游戏？

我2年前写的，有点幼稚。别见笑
VERSION 5.00
Begin VB.Form Form1
AutoRedraw = -1 'True
Caption = "打字游戏 小游戏而已"
ClientHeight = 4800
ClientLeft = 60
ClientTop = 750
ClientWidth = 5610
LinkTopic = "Form1"
ScaleHeight = 4800
ScaleWidth = 5610
StartUpPosition = 1 '所有者中心
Begin VB.Timer Timer1
Left = 0
Top = 3600
End
Begin VB.Label Label1
Caption = "Label1"
Height = 735
Index = 0
Left = 1320
TabIndex = 0
Top = 600
Width = 855
End
Begin VB.Menu MenuGame
Caption = "数量 (&N)"
Index = 0
End
Begin VB.Menu MenuGame
Caption = "速度 (&P)"
Index = 1
End
Begin VB.Menu MenuGame
Caption = "重置 (&R)"
Index = 2
End
Begin VB.Menu MenuGame
Caption = "开始 (&S)"
Index = 3
End
Begin VB.Menu MenuGame
Caption = "输赢 (&W)"
Index = 4
End
Begin VB.Menu MenuGame
Caption = "帮助 (&H)"
Index = 5
End
End

Rem 自定义函数效率不高啊。。。
