Okay I finished Summer Pockets and the true ending is really underwhelming, it suffers from what I like to call "true ending heroine" problem. Which is when the game has multiple heroines but the ending pretty much locks you into one for a full conclusion, making the other routes feel pretty pointless besides some background info. Sometimes it's done by the "true" love interest which sucks extra hard because at least with a canonical main route love interest you have some sense who she is beforehand. Summer Pockets is thankfully not the case but it feels extra forced because the true route is a Clannad sort of post story which has dire consequences if other heroines are chosen, which speaking of, have their issues apparently solved in the other routes despite some issues being literally impossible by ordinary means. The true ending itself is a bit repetitive though it did get me tearing up.
It's overall an alright game, not as much as a tear jerker as other Key games and I liked all the characters and most routes. Which makes it a good summer game.
