I had fun with this die and retry! I found the arts and effects pretty cool (good choice if it's not yours), same for the music.
I didn't go very far during my first games, but i've seen the great diversity of enemies, well done!
In my opinion there really misses a sort of points system, who i think, will fit with the gameplay.
About the themes, your appropriation of "space" is pretty cool, and different of what i've seen until now ;) 👏
