Thanks for your feedback.
Actually, the game was originally designed for the GGJ competition, but there wasn't enough time to finish it. So I adapted the idea to suit the competition and its theme: there's a reality mask that lets you see things that aren't there (the player was supposed to see more, but there wasn't enough time to add them). As for the pause menu, I completely forgot about it 😂.
But I expect to finish the game soon and release a full version.
