I tried it, but it was nothing special, just hard to understand the game concept as nothing is explained in game, only as text.
The art doesn't stand out, the game concept itself is not really interesting (might be new) to me. The best games hook people into the game loop with something special or unexpected. I didnt find this in Hollow Castle.
Clicking wildly made me look like I do progress, but nothing warns me that I am just about to lose for not playing it correctly.
Correct me if Im wrong anywhere please.
