Cool idea for a game! I really like the idea of being trapped in a game by bad programmers and being able to escape because they made it poorly. The inclusion of the debug menu/command prompt was a nice touch, since it showed that the game was actually breaking and having real errors (but in a controlled way), although this technically couldn't be shown on a Nokia.

I have a few criticisms:

The game says that dying isn't a bad thing, so I didn't expect to get a game over and have to sit through the entire intro cutscene after running out of lives. I know there's a bug to get infinite lives, but I feel like that should just be the default setting instead of needing to be activated.

I also feel that the text should progress when you press a key instead of being on a timer. This way you can read it at your own pace the first time, and skip through it quickly the next time. Also, the font should be changed a little, since some of the letters are hard to make out.

In my opinion, the text shouldn't progress automatically, but at a key press, so that you can read everything and skip it faster later. For some reason, when I went up in the first room, I had to wait a very long time. There are quite a few grammar and vocabulary errors in the text (but I understand since I assume you're Portuguese). 

Nice!
A really cool game mechanic. But intro should be skippable after you die.

Overall it's a great and fun to play game :D
