A quiet, introspective puzzle game where you gently draw lines to unlock a coded love letter.

What players say
Players say it is a short, polished puzzler that takes about an hour, with 30 levels compared to its predecessor's 40. The letter-decoding gimmick divides opinion: some find it a sweet motivator, others say it spoils puzzle solutions. Most find the game relaxing and not too difficult, though a few levels spike in challenge.
