Thank you very much for your words and feedback! I`m thinking to add more levels, somekind of little story, other block types and visuals, and a couple more of mechanics (something simple and fun) to get a little game for this poor lost pixel XDD.
Yes! in the credits scene there are two players... I forgot to erase one (it was planned to have a companion and a short intro story, but this was imppossible in a 3 hours game jam XDD). GDevelop has capacity to introduce an option of multiplayer... It could be awesome to have the option to compete in reaching the top (in a physics game like this could be very fun to see).
