If you're using windows:
You have to extract it first. You do that by clicking the file once, then the three dots on the top right of your file folder, and then pressing extract and accept. After it loads you double click the TADDS with the little lady icon next to it.
Some games don't name their little lady icon, and its instead called (something) 34, which is irrelevant to this game but needed knowledge if you want to download other games on itchi.io. Always click the little redhead lady. Though sometimes creators will put in their own custom picture for the game, but you should be able to recognize it anyway because it'll match the vibe of the game you're downloading.
Also Also, don't place the icon on your desktop. When you open it that way, it doesn't always work.
The control button lets you skip dialog btw, and escape will lead you to the save/load screen.
