The game's story was pretty interesting for me, there's drama and romance there. The only problem i have was there is no save files, trying to get a different ending without save files was really a pain for me (for anyone who wants to complete all ending : I discovered that if you quit during the important choices cutscenes, notably the last one at 1200 affection mark, you should be able to go back from the start of the cutscenes and try out different answers). And it seems that the player's choices except for the last cutscenes hardly affect the story, so that's quite unfortunate. Other than that i have no complain, the story does a good job on developing player's relationship with Airi/Iri. I'm satisfied and also uneasy about that one bad ending.
