Level Select

Russian	Translation
Экран кодов: Если это вы читаете вы либо читер, либо великий разработчик этой игры. Ну что выбирай раунд смертный!!!	Code screen: If you are reading this, then you're either a cheater or the great developer of this game. Alright, choose your round, mortal!!!

By pausing the game and pressing the up, down, right, and A buttons at least 25 times each, a secret message from the developer will appear and will then let you choose from the 16 stages in the game. This stage select is also seen in other games developed by BMB but with different buttons required to access.
