Hi,
That is ok, thank you for the feedback. apologies I should of been a bit clearer with the game controls.
If you ever attempt the game again, the control is just spacebar, nothing else (execpt the mouse to press the restart button), if you need to jump higher just hold down the spacebar. I also recommend trying to jump closer to the object for a better chance at clearing it. the game moves automatically on its own and speeds up when it progresses.
if you find that you still are unable to jump over anything then it might be a bug.
thank you for attempting to play.
