This is definitely an interesting concept, a platformer where you can move only in one direction although this game is a little bland, but as I read from the description this is your first 2D game, and it's pretty good to make a procedural generator platformer for your first 2D game, and also you intended to have enemies, which would have spiced up the game, the game is a little bland in it's current state, but I must congratulate you for not giving up and for #finishingit :D, can't wait to see what you make next :D
