The project has a nice foundation for being a really nice game, however it needs a lot of polishing and tweaking to make it satisfying to play. You are on the right track so just keep working. I would make the character a bit faster and more responsive, like the jump should be less floaty (I suggest implementing jump strength, you can find it on forums) like Lithileix said, the character should jump and fall quicker, everything should happen at a fast pace in my opinion and then it will be a lot of fun!
thanks, this is a first prototype for testing the mechanics of the game, i will modify the jump and add the strenght to make it better, im working with a developer to sort this things out
thanks for the feedback!
