You are a really creative person, hope you keep on making more and more amazing games moving forward ! One last thing: Would be cool if you added this game on steam. More people would see it, but since the game's content is like that (with a Dev's journey as the plot, I could see why you wouldn't want to share it on that platform. Anyway, good game.
I haven't played it myself and only saw the video, but if you decide to put this game on steam, I'd suggest leaving Dong's story as a text / speech in the game, possibly before the main game begins. It'd make the game much more enjoyable for the player.
Good luck, man <3
