Hey!
Good submition for a first try!
The minimap, the procedural generation and the story are definitelly plusses.
I would have loved some audio for the game, even juste a free sountrack, try to prepare a audiomanager so you can reuse it easily between jams (a music bus with a background track and a sfx bus with somme sound effects triggering by signal are great to have in a global script)
The wasd is not very practical for us weirdos that use azerty keyboards, the ability to rebind stuff feels good. it's also quite easy to implement from one game to another, you will build those feature as you keep jamming.
Have you done the art yourself? I don't feel like it is but I'll be glad to bump your score if you did so tell me ;)
Keep at it, it's a good start!
Cheers
