Oh, managed to figure it out. I wasn't aware that you can hold the jump key for a slightly higher jump so I initially got stuck at the beginning when the third row of red bricks appear. You should include a hint that says "hold jump for higher jumps", or something like that.
After I figured that out I was able to finish the game. It's short but smooth and very playable. Got a bit frustrated at the end when you have only a small window of visibility.
