Good replayability with the the time pressure, resource scarcity, and relatively strict game balance shifting the rpg grinding from a forced conceit of the genre into an optimization puzzle leading to NG+ rewards that add enough to avoid monotony on repeat playthroughs without breaking the game balance. At the same time, these things do make the game a bit linear
That being said, the lewd route seems a bit too pressed for time as a resource; trying to get a good lewd score felt like it got in the way of making progress on the game's plot or gaining stats. Combined with the pink run having a lower score potential than the pure route, I'd say there need to be more ways to boost one's loserscore.
