Yo, I guess everyone can make their own decisions but I feel like that's kinda unfair. If you don't understand the controlls or the theme at first, you shouldn't imedeatly give a low score. Not only are both the theme and controlls explained on the itch page, but you can also always ask the dev first for help (or just don't rate the game). That's just my opinion, but maybe don't jump to conclusions that quickly.
Have a nice day :)
