A rather mediocre experince.
From the start the game gets off to a rocky start. The voice acting all sounds rather...well they sound like crap. Plus this game has almost no action. Theres the time when you run away from the enemies like once or twice. After that, thats about it. And when you have to search for a weapon, I had to crawl all over the place before I gave up because I didn't know what I was looking for looked like and resorted to the jump menu relinquishing all my hard earned Sprite Droppings.
But I'll give you credit on the story, it does seem interesting enough and at the beginning I did actually jump once or twice. But in the end, this series needs alot more work before it reaches a level where it can be considered great, or in my opinion, good. I would suggest that while keeping the dark theme, in the next game also include more action. And if someone seems to be stuck on something, include some clues through character dialogue maybe. And also try to cut back on backtracking, the amount of backtracking in this game did kind of piss me off considering how big the entire cavern was.
I hope you take some of these things into consideration when making your next game to make it a more pleasent experince. I'll make sure to watch out for it.
