Thank you for trying out the game and for the feedback! Yes, I agree with you that the firefly catching could be better. Internally, the game checks for fireflies in front of you in a cone-shaped area, and I think as they get closer to the lantern (the tip of the cone), that area is smaller and so they can drift out of it, which isn't the smoothest experience. You end up having to take a few steps back and reorienting yourself towards the firefly again. Time constraints deprioritized tweaking this though, I was running up against the jam deadline!
