Windowsill Wizard

A wizard on your desktop

Windowsill Wizard is a PC idle game about Pell, a small wizard rebuilding a ruined tower at the edge of your screen. His master has gone north to keep a fallen star warm, and Pell stays behind with a spellbook. You choose the spells he casts; he works through them while you get on with other tasks.

The tower sits along the left or right edge of the taskbar in a window no bigger than the tower. Clicks on empty pixels around it pass through to the window behind. You can keep the tower on top, turn that off, or use a framed window. It hides while a fullscreen game or video is running, then catches up when you return.
