小時候在公園玩「踏影」——跳起來、踩中朋友的影子才算；躲進樹蔭就安全。長大後一直想：能不能在電腦裡再玩一次那種黃昏的快樂？於是做了這款小遊戲。
As kids we played shadow-stomp in the park: jump, land on a friend's shadow to tag them; hide in the shade and you're safe. I grew up wishing I could feel that dusk joy on a computer. So I made this small game.
跳起落地踩中對手影子才攻擊；躲在陰影裡沒有長影＝安全。
Stomp on landing — only a jump-landing on their shadow counts. Hide in shade = no long shadow = safe.

遊戲免費。若你也懷念那種在燈光下追影子的晚上，願意請我一杯咖啡、支持我把《踏影》做得更好，我會非常感激。完全自願，不捐也能爽玩。
The game is free. If you also miss chasing shadows under the lights and want to buy me a coffee so I can keep improving Umbra Step, thank you — truly. Optional forever; play without paying.
