Not a terrible concept for a game but I feel in it's current state its a little more frustrating than fun. I think a screen telling you what exactly you are doing would help a lot. 

I keep hearing clanging noises that weren’t in the tutorial, but I keep holding the button and keep hearing stepping noises. I think they’re the slot machines and the dealer’s table? Why do I still hear stepping noises – am I bouncing off of them?

I beat all 6 levels! It was frustrating at times; here’s some specific wishes I had:

• I wish the dealer shuffle sound only played when I was close enough to win – at the start I kept hearing it and pressing space which would reroll the floor for some reason, and thought I was winning.
• I wish it showed me where I was (and maybe the entire history of my path?) when I got caught.
• It was a bit annoying with all the guards around. It seems like there’s probably something more interesting than guards that you could use to add difficulty – maybe maze-like levels? I dunno

I liked finding myself based on sound alone – it’s like I start with a quantum state of being everywhere at once, and then I use the sound clues to slowly collapse that down into a single position. I enjoyed the game! very different and fun. reminds me of Invisigun Reloaded and https://gruebite.itch.io/double-blind

Premise/instructions of game from game page: A game where you must determine your position and then make your way toward the goal using sounds alone. Your goal is to stand near the Dealer and press Space Bar to advance to the next level. Move with Arrow Keys or WASD. After the intro, you will be invisible. Use the intro to familiarize yourself with the sounds. Sorry, there are 2 carpets that make the same sounds.
