You got it right to restrict your idea: you get a interesting game in only 4 days! To improve your idea, you might want to check the surrounding to the player. When the gravity change, you might fall outside of the world (and so dying) I feel dying because of that is a bit frustrating. You might want to keep that for latter in the game?

Sorry: I checked again. Actually, it's kind of lava! I think I didn't saw it when I played because the color are not that different from the other side. But my command is still valid: Doing a miss fire at the beginning of your game will put you in a very bad position, while you just started the game for the first time. Could be great later in the game.
