you can press h to open one help manual and m to open a different one. To select an option, press down until the blue arrows are next to that option, then press space. At the beginning, you are in a prologue where there is very limited card battling and you have no deck. You should talk to NPCs by walking into them and interact with objects in the same manner to figure out the plot and your character's identity. You move with the arrow keys and cannot move diagonally (except via glitches in a handful of circumstances). There is no consistent way to tell which tiles are walkable and which aren't, but you can walk on any tile an enemy walks on and the tiles with three horizontal lines tend to be doors. Screen edges mostly lead to new maps if you can walk on the spots next to them, but not always, and sometimes only from certain spots along the edge. Things that flash yellow are important. You fight enemies with cards, and get 2 actions per turn. If you encounter an enemy near another enemy, you may get a single fight with both enemies at once, which is usually bad but sometimes good. Your goal is to stop ZoZ but it's actually to get married but its actually to negotiate the boundary between a post-apocalyptic anarcho-communist society and a dystopian late-stage capitalist one in a coming-of-age adventure story.
