It has fresh new elements based on traditional puzzle/board game. totally free.
if you like traditional puzzles like sokoban, mummymaze, then try this forever free game.

Happy lives are alike while tragic life differs, we have made this game with my team in this cov19 year, with nearly no financial support from any people, and just hope to get someone to play and get your feedback.

Thanks and regards
Jimmy.
