I love that you have a README and License file (main criteria for open source category). Next step would be changing the Phaser template to reflect your game; add some screenshots and info about what you built. You can even add it directly from your submission page: https://l4sh.itch.io/log-legend.
Interesting take on the theme. It wasn't immediately obvious that the character had his back facing to me, so I was confused (for about 1 second) why my step count wasn't going up. But a second take make it much more obvious and the controls are simplistic, intuitive, and easy to get the hang of. I enjoyed that the game starts easy and gets harder.
Add some music and sound effects to make this game even more immersive. Great job on your submission.
