Overall, not bad. Starts out as a gag manga, then gradually moves into serious themes and character interactions. Ends with the beginning of Chapter 5 in the game.
The later chapters are quite good, easily better written than the entirety of the Hikari o Tsugumono manga. Every recruitable character from the first generation has their time to shine (and it highlights some of my preferred ships, so that's nice). The gradual transition of tone is handled well, so there's no danger of mood whiplash with the gradually less frequent gags.
