Double Homework

A story about a guy undergoing a very tough time in his life, due to an incident that literally changed him forever. Fortunately, he lives together with two girls, and he focuses on trying to break the bad cycle he has fallen into.

Double Homework is organized in episodes. Each episode is a stand-alone game, but all of them share the same data and keep your progress. The game is made using HTML5 and therefore it runs well on any platform with proper WebGL hardware acceleration support, including Windows, Mac, Linux and Android.

Supported browsers: Google Chrome or Mozilla Firefox.

Mobile support is currently in beta and issues can potentially appear. The only supported browsers for mobile is Chrome (Android). To get full screen, open the game, tap the options button of the browser (“…”) and select “Add to Homescreen”. This options is also available on iOS under the share icon (Safari). Due to limitations imposed by Apple, the game may not run well on iOS devices.

Important: do NOT minimize the game while playing on mobile, as your system may kill it and you will lose your progress. Make sure to save before you leave the game.

Please email any potential issues you might encounter to [email protected] or preferably on our Discord channel (bug-report section). Note that you might see a black window for a while until the game loads. Consider closing your other browser tabs before playing. If the game feels laggy on desktop computers,  make sure your system GPU drivers are up-do-date and that “hardware acceleration” is enabled in your browser settings.

Double Homework has a variable editor that allow players to easily change previous chapter’s choices. It is also useful in case of data lost.
