Pretty fun game! I like the music and the idea behind it, reminds me of some good ol' RPG puzzle games.
Two things though, 'r' doesn't seem to work on the last level, and babelfish couldn't translate "Obrigado" from the ending, although I assume it means thank you.
I'd like the see a 'second' version with more levels, more polish, and maybe the option to play without effects.
