Relevance to the theme.... naaah... ok :D The controls are a bit strange although you explain them in a very well made tutorial part. You can't really stop the character moving and this makes the game very hard.

1. Tell us about your game. (The story, setting, theme)  

You're just a miner trying to get out of a cave, until you see a grappling hook with only 2 shots in it

2. Tell us how your game fits the theme.  

the puzzles and platforming challenges revolve around having only two shots with your grappling hook, so you gotta count on those 2 shots.

There's also puns revolving around the word "two" that the player character randomly says

3. Mention any assets (with links) used in the game that was either taken from the internet or made before the jam began.

All assets and scripts used in the game were made within the 48 hours. Except for the Unity game engine itself, obviously
