Very pleasant solid RPG. Heartbeat has a lot of likable characters and a very comfortable atmosphere aside from when it gets serious at the end. The writing, while nothing extraordinary, is entertaining enough and doesn't fall into the expected indie trap of characters trying to be quirky and make sarcastic jokes every other line. I was also pleasantly surprised by the sheer amount of well-done character designs throughout the game, a lot of which belonging to characters that didn't even get much more than a couple scenes to talk. The artsyle is very nice and I like how it's clearly anime-inspired but with enough of a western touch that feels different without going into tumblr territory, kind of like crosscode. The music is good though the sound effect for clicking on options can get kind of annoying. The battle system is a solid iteration of JRPG-like turn-based combat and it does a good job of making you want to use status effects and buffs/de-buffs though enemy HP can be a bit too high sometimes, especially in the early game. While the combat is good, I do feel there's a bit too much of it, particularly in the finale. The story is decent but I wasn't emotionally invested. I was also greatly annoyed by missing the requirement for the true ending and having to be set back by a decent amount of progression to get it. Aside from that, I don't have many complaints about the game besides not getting to choose your party members throughout the game, or at least one of them and only making you use Eve, Klein and whoever is relevant in the story. I'm also kind of disappointed there's hardly any feminine characters in a game where nearly every major character is a girl. Pretty much every party member besides Io and Stolas have the appearance of a standard anime boy.
