This is such a cool idea! The only thing I would say is that I think the light range around the player should be a little larger. By the time I got to 5-5, it became difficult to see when the moving F capsule was nearby. Or at the very least, allow the moving F capsule to move closer to the player. Additionally, I think there should be a larger buffer room for the timing and range of pressing F to land inside of the capsule; the buffer room feels a little too small, which made it more difficult alongside the current light range. Overall, this is such a cool game and a great idea!
