A really, really good game!

This is a really good little game with fun and challenging puzzles, wonderful art, a great spooky atmosphere, and an intriguing story. I'm really looking forward to the upcoming chapters to play more and see how the story develops. As others have said, it's short but it's only the prologue and it's free, so no problem there. Gameplay worked well for me.... quick transitions and a responsive interface. I only had one issue which was with the clue for the drawbridge controls... I didn't get that clue at all.... don't see the relationship of clue and puzzle and needed a walkthrough for that one. I had played at first at 'hard' level and went back at 'normal' level to see if it was any better at that level and it wasn't. As another player has said, the hint didn't help.... it only told me what I already thought.... and then gave the complete solution. Even after seeing the solution I still don't understand how to interpret the clue. But still five stars because, other than that, it's just so good. Thank you developers! It's great to see a new dev bringing such quality work to the party! I'm ready for more and will be on the lookout for your future endeavors!

Awesome start to this game!

Excellent game! I’m a big fan of HER Interactive Nancy Drew mysteries and there is currently only one available for IOS - worked through it, loved it, and wanted more to play on my iPad without dragging out my whole laptop. This one reminded me a lot of those games and is exactly what I was looking for! Like everyone else, I needed help with the lever challenge, but it seems that issue is being addressed. Otherwise, awesome game and I’m looking forward to more chapters!

Good game, very promising start!

I finished this yesterday, it’s very short, probably will take about 30 minutes to an hour to complete, but it is a PROLOGUE, and it is free so I don’t have a problem with that! The storyline is very interesting and I Iove the eerie atmosphere and music. I’m excited for the future parts!

(But the arrow hint for the lever puzzle didn’t make sense to me?)
