I love this game. Thank you so much for making it. I want to write a longer review at some point as a better "thank you" to the devs, but the characters are great, the music is fantastic, the battle system is engaging and challenging the entire game, the art and graphics are outstanding, and everything is charming in a way so unique to Heartbeat itself. It's just a fun, fun experience that brought to mind all the GameBoy Advance games I used to play when it was around.
I find the game to be very well-executed overall. There's a few places where I would have liked to have seen more--maybe more or better-developed puzzles, or perhaps more sequences where the battle system itself is changed up, or maybe ways to make fish and EXP grinds a little more interesting--but overall the game benefits from its relative simplicity. I really enjoy the writing and the story, but I always felt like I wanted more of it. There's the makings of a great tale about wronging and seeking forgiveness, and being wronged and forgiving, but it's slow to develop and underdeveloped by the conclusion.
None of that takes away from just how much fun it is to be playing the game. I would encounter new enemies and send screenshots of their designs to my boyfriend as I played, I'd hope to hear certain music tracks again, I'd hope to get more dialogue from my favorite characters (namely, all of them). It's a beautiful experience full of warm colors, lively characters, and great personality. It's also perfected the lost, difficult art of the boss rush, and you get to feed the cutest little baby moth ever. So, I hope I get to have more experiences playing games like those I had playing Heartbeat.
