Infelizmente não e vou ter que voltar do zero porque vou usar outra linguagem.
Nos meus primeiros dias aprendendo Ruby eu finalizei um bloco da notas e um gerador de senhas, recentemente eu fiz um jogo da cobrinha que segue regras bem únicas e ele funciona no terminal (nele eu usei as gems Curses, para dar mais estética ao terminal, e Set, pra ajustar a localização das armadilhas sem ficar por cima dos pontos).
Se quiser ver, o código é esse:
require 'curses'
require 'set'
