Sweet little game! It was quite easy to understand the mechanics, which was great in itself however the overall experience wasn't that challenging. All levels was completed with very little failed attempts. But I think the simplicity of the game allows for some really good puzzle levels, especially if you consider adding one or two extra game mechanics to spice it up! I myself am making a similar tile-puzzle-game, Freestile, which is avaiable on my itch page. Feel free to check it out and perhaps get some inspiration if ya like :)
