Very fun game to play. I didn't see an issue with the overhead block, as it becomes a challenge to work out how to avoid it slowing you down.
The bouncy feel is amazing and adds to the frustration you feel playing the game, along with some of the jumps being difficult to complete which feels like it juxtaposes the title of the game.
All in all, great game to play would be fun to maybe have alternative paths and more levels.
