Thank you for letting me know. unfortunatly I have stopped development on this game, so this will not be fixed. the game should on the other hand work a lot better on PC. Also on android phones with 16:9 ratio.
Have a great day!
I just released an Android version of my game Submarine Samurai. Its a casual sinksub-alike with power ups. Get it here: https://madduckgames.itch.io/submarine-samurai
This is a simple retro flirt type of game. You control a boat on the sea surface trying to destroy as many submarines as you can over endless amounts of levels. You can also pickup powers and extra lives to help you get a higher score for the leaderboard.
