花费了好几个小时，我终于是找到了第20个涂鸦，本以为会有有趣的东西等着我，结果是无事发生！甚至连成就都没有弹出！我非常失望
Hi! The game is inspired by an artist, so I really tried to fit as many references to him and his works as I could fit into the game.
It is true I should have had some kind of reward for collecting everything! Maybe in some future update, if there is, I will come up with something.
Thank you for playing and for your perseverance :)
