I can't really answer most of the ones about control well maybe exept that you can quit the pause menu with esc it's just that you have to be in windowed mode because itches fullscreen takes priority otherwise. The game has lag spikes on browser that's why a windows build was provided for those who find these anoying. If it comes to the theme you could take it on the base value inspecting stuff makes it bigger but there are also story beats later on that are on theme
