I think you've found a very interesting solution to represent depth with light! That said, I still don't know when I would hit a block moving side to side! Overall, the game is addicting and fun! Well done!

It feels a bit too unfair with the bars getting bigger and I believe to be different sizes when they are at their biggest. It makes it very difficult to judge what action to take. Maybe by using a color code and having three different sizes the player may find it more fair.
