Steam Store description

Koibumi . It is a letter confessing love. A so-called love letter. All you need to convey your feelings is love, courage and a little luck. You become the love letter and deliver your feelings to that girl. Whether this love will succeed or not is up to you. Objective of the game: You control a paper airplane and fly through the sky to deliver your love to her. However, the paper airplane is fragile and if it hits something, it will crash and the game over. If you just want to deliver it, it will be easy. It may be difficult to collect hearts and fill them with feelings.
