Wow, there are many ideias right way! The part about "replay the tutorial" is a very interesting idea that I've never stop to think about it. We will surely add some option to read the tutorial again. And also, the game is under development, although it's a demo, the project itself will have much more upgrades.
E pode deixar, testaremos seu jogo sim, queremos apoiar mais projetos indies brasileiros. Obrigado pelo seu comentário! :D
