I love that you have a README and License file (main criteria for open source category). Great use of screenshots and emojis. Nice comprehensive README.
Full screen on load is great! The main menu has nice clean graphics, animation, and I'm enjoying the music too. I love that the text is super easy to read.
Great work on the narrative, again, all the text boxes are nice and easy to read (relatable content too, and I'm enjoying the art style). It'd be awesome if there was an option to speed up the typing speed (it's great you have the "skip" button, but I also like to read text really fast). the slowly moving background is also really nice; not distracting, just a nice touch.
The in-game menus and things are amazing. Perfect use of text; not too much, easy to read, good use of colours and emojis. The music and the "timer" being the little dude on the bike is great. The Noodle Ranking Empire concept is great. You really went all out with this and super polished game. Nice work.
