One Button Warrior

Install and open the downloaded folder. Double click the OneButtonWarrior.exe or OneButtonWarriorHD.exe respectively. You will be prompted to extract the contents, click yes. In the newly made folder double click the same thing as before and the game should run. (After extracting, the OneButtonWarrior.exe or OneButtonWarriorHD.exe should have a picture for an icon.) If you are having troubles opening it from the bottom of the screen after downloading, right click it and click keep. If windows prompts you that it may be harmful to your computer look for the option run anyways.
