Hey, thanks so much for your kind words! I'm happy that you enjoyed the game.
You have to make your way to the far left where the well is located and then continue on the lower half of the screen towards the right. All the guards have certain timespans, where they're distracted and won't see you unless you get too close to them. So make sure to keep your distance and observe their behaviour. I hope this helps, otherwise feel free to ask! :)
