Rather than only sharing my development progress on this blog, I’d also like to participate in game jams like this in the future.</p> <p>This year’s theme is <strong>“Unicorns and Rainbows.”</strong> It’s not a theme that I’m particularly familiar with in Japan, but personally, it reminded me of the time when MLP (My Little Pony) and bronies were popular.</p>Game Developmentrainbow-speedjs13kgames
