The paper-diorama-style always is super charming! The art is cute and well done. I am, however, having a bit of trouble figuring out what to do after the fairy h-scene. I am on Linux running through Wine, so it may be bugs induced by compatibility layers.
At first, I wasn't aware I was supposed to interact with the characters multiple times, but I got the gist of it quickly. The animations are super smooth! The fireflies around are a super nice touch.
A minor issue is that the character's animation faces the wrong direction. For example, when walking North-west, Timmy faces east, and when walking south-east, Timmy faces west. It is hardly game-breaking, of course. Also, sometimes the H-scenes fail to load, with just a black screen and a "skip" button, but the game seems to recover from that issue well.
Overall, this is a nice cute game and you both should be proud! I love the smooth animations, the art, the running away from the dark fairies, and the h-scenes are well done.
