As the title suggests, it's not a bad game. It could use some work, but it's okay. It lags a lot. That's kind of a given- the crumbling of the tower on the bottom can't help that much.
The clouds that come in when you go up also can obscure your vision of the next jump- either make them more transparent or remove them entirely, please. They make it so I can't tell what I'm doing.
The aesthetics, for lack of a better word, make it feel like you are rushed to hurry up and think of what you need to do, but in reality you have a good few seconds to process what you're doing. I personally like this- it's a lot more forgiving, and it helps when you get stuck lagging, but it still feels like a fast-paced game.
My high score is 34, but my average is prolly around 17, heh.
