About this game
This is a programming game that lets you experience the work of a gameplay programmer.
Throughout the game, you will build the core mechanics of many different games while following the story of a game developer, partly inspired by real experiences.
If you are already a game developer, perhaps some of these moments will feel familiar.
If you hope to enter the games industry, or are simply curious about game development, this game may give you a glimpse into the work and life behind making games.
If you simply enjoy programming, puzzles, and intellectual challenges, I hope you enjoy the satisfaction of solving each problem and eventually realize: You can now make a game on your own.

Patch NotesOfficial
0.5.3 Update
Hi everyone! I've updated the demo with a few changes to make the editor easier to use and give you a hand when you get stuck.A new editor guide walks you through the task panel, font size, Run and Submit, panel resizing, and output. It appears the first time you open the editor, and you can replay it from the guide icon on the left.Editor improvements include a shortcut for commenting and uncommenting lines (Ctrl+/), output text that follows your font-size setting, and fixes to cursor movement, text selection, and autocomplete.More help in the levels: some levels now have expandable hints and code examples. I've also updated the User Manual and added clearer guidance for debugging and checking results.Book reactions let you leave a reaction while reading and see the community's feedback.A visual refresh for some robot and box-pushing assets, avatars, and news images.I hope these changes make it easier to get into the code and keep exploring. I'd love to hear what you think in the Steam discussions!Read full article on Community Announcements (W.Y.Games)Patch NotesOfficial
0.5.2 Update
A few small UI and user experience improvements.Also added a new tip to the level completion panel:“Code lines and efficiency don't have to be perfected in the same submission.”Hopefully this makes it a little clearer that you can optimize them separately.Read full article on Community Announcements (W.Y.Games)Patch NotesOfficial
Windows Display Issue Fix
I found a Unity bug that caused the Windows version to appear darker than intended. The issue has now been resolved through a Steam launch configuration change. No action is needed from players. Just launch the game normally through Steam.Version 0.5.1 also improves the music player UI, adds new dynamic visual effects, and remembers your previous playback state.Read full article on Community Announcements (W.Y.Games)Patch NotesOfficial
