That feels quite good. The movement of the space ship is good, and the smileys fire nicely. Now you need to decide what the challenge is. If the task is not to get hit by the balls, then there are too many - you just cannot escape. If you leave it as it is (you can crash into the balls without damage to the ship) then the question is what the task is...

Okay, here's what the Google translator makes of it in its attempt to get the instructions into English: "Nemus must go through all the pyrañas so as to arrive at the delay. Can hide in the algae that are found across the stage."

No objects? You have to write code in your world's constructor to place the initial objects. (See some other scenarios for sample code.) In the exported version, we cannot interactively create objects...

Nice! Cool new opening sequence, and I like the handling of losing a life (without the separate dialogue box) much better too. And I finally got across! If you wanted to make it just a little bit harder (and more interesting), you could make the middle row of the cars go at a different speed (a little slower or faster than the other rows). Nice game.
