It has a nice art style, an interesting control scheme, some fun puzzle mechanics and a short, dark, abstract story told through collectible memories scattered throughout the game. You need to find them all to unlock the final chapter.

It also has plenty of intensely frustrating parts where your actions and timing have to be perfect or you will die. Checkpoints are always a little further away than you would like.

Most notably, randomness of chapter 2 boss actions and falling debris followed by the completely unintuitive thing you have to do next.

Chapter 4 ends with many rounds of a follow the card game (the dealer isn't cheating, but speed is ridiculous), and the briefest glimpse of a silhouette passing which you have to match with one of four options. You can only get so many wrong before it restarts and it feels like it will never end. This is random, no patterns to learn or clues to be found. You have to be very good at tracking fast movement or very lucky.

Chapter 1 and 3 bosses are easy, chapter X is easy once you figure out how the different fireflies act.

Generally, I found it best played with a controller, but there were a few spots that are much easier with a mouse to guide the firefly to a specific place on screen. Selecting one input method in the options will disable the other, controller is not enabled by default.

I came close to quitting many times. Between the frustrating parts, I liked it. It gets a positive rating, but only just.

Runs perfectly on Linux with Proton. Do not set the in game resolution higher than 1920x1080.
