At my first try I try not to look anything at page to see if a game could tell itself. So i was just pressing buttons and very pleasantly surprised. I just played with the colors for a minute or two. It looks and feels great
Sound and music also works great. I am not sure but maybe procedurally generated?
Developer/s clearly know how to code and give attention to the detail.
Now hot seat games are hard to judge by game play when you can't actually play but I hope I did my best.
