It's a neat little puzzle game, I love the concept. If you do choose to continue with this I would recommend a short tutorial to introduce the concept, maybe give a short little story as well haha. In my opinion, the controls felt very slippery and the ads moved as if they were on ice, which was very jarring. If that was your intention, I'd recommend making the ads smaller and the space bigger so you can use that as a main mechanic within the game. Also, towards the end there was this blue "powerup" thingy that just sat on the screen. I picked it up and I have no clue if it did anything, so unless it literally does nothing, maybe explain what it is? A real clever way would be to have an ad of that blue thing in that same level, that way you can explain what it does and it still fits within the game theme. Other than that, not a bad game.
