This game surprised me to be honest. At first it seems like a simple mechanic that I have seen very often (jumping as resource). But the game design and execution is what takes this to a new level.
First I love the sound design (besides the jetpack, it sounds a little bit like the character is farting :D) the sound effects make it really immersive.
Then the level design is pretty cleaver, I love how there is often a "obvious" way and a right way. It really felt great after failing to find a alternative route that was the correct one.
And at last the atmosphere, wow! when the light got out I completely expected some monster.
This game does a lot of things right, I love it !
