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!

Fantastic game with great atmosphere

I have spent thousands of dollars on IPhone games over the years, often just to support the developers who thankfully haven’t turned to the dark side(“free-to-play”) This game is actually a FANTASTIC point and click adventure and is absolutely worth atleast a couple bucks. Brilliant move making the prologue free, as hopefully it will allow players to see how great a game this is and hopefully invest in the future chapters. I have already purchased chapter 1 (havnt started yet) and will absolutely be purchasing every chapter released.
Great hint system, beautiful graphics, interesting location and story, and pickup objects are not overly-hidden. It’s generally fairly apparent which objects can be interacted with, and you always feel as like you are making progress. Amazing game, and I absolutely recommend everyone atleast try the prologue, and if you enjoy it, support the dev so they can continue making actual good games, and not the freemium b.s. that sadly is flooding the market, replacing actual fun games. 10 out of 10 for this guy👍🏼

Great! Except...

I loved this game! It was challenging, beautiful to look at, and engaging. However, like other reviewers have stated, the lever puzzle and hint were confusing. The hint showed arrows, stars, and a map that (to me) had nothing to do with the levers themselves. Plus, I already fooled around with the levers before finding the flag clue, and when I returned to the panel the levers hadn’t reset, but instead remained where I placed them, which threw off the sequence in which I should have pulled them. Unfortunately, I had to skip the puzzle altogether. The only other thing is that the game is disappointingly short, but for a free “prologue” I guess 20 minutes to complete isn’t bad play time. Good overall!
