Good movement mechanics and some fun levels. The level design could be more challenging to test the player's grasp of the great movement mechanics. For example, having a tunnel of spikes so the player needs to maintain flight and balance fuel usage while dodging some enemies along the way would be challenging, tense and exciting. The writing is witty and fits the overall atmosphere of the game. Although the self-awareness of the writing could've had more personality if it was assigned to a narrator, the player or an omniscient being. For example, instead of the introduction flipping between a narration and the subconscious of the player, have it be assigned as a narrator. The narrator could end the introduction with a self-introduction like "By the way, my name is Harold. It would be nice if you could remember me."
