The presentation is amazing, however the shooting system ruin the experience a bit.
Personally I would remove the shield and use a button to jump (or a jetpack style mechanic) and another to the shot.

Thank you for the feedback, i understand the controls being confusing at first but we decided this method would be best as it free's up the right mouse for any other extra game play element, we do plan to update this game after judging is over to express the original intention of the secondary button.
