There is a nice atmosphere for something as simple as a flash game.
Unfortunately that atmosphere is ruined by the unfitting music that would be better served in a Facebook Cooking application. It does not feel like I am trapped inside a Catholic church, whereas something ambient certainly would help me to enjoy it more.
The puzzles are relatively well done, however, I constantly find myself dragging dozens of circular objects into the dozens of circular holes to see if they fit. There is no clear indication of what each objects intended purpose is, not to say that they should necessarily, as that would defeat the purpose of the games; however there is a certain frustration caused by the repetitive strain of placing many objects that would logically fit into many different sockets of the same type.
If there were more variety in puzzles, as opposed to reskins of the same thing to amount for gameplay value it would feel a lot richer.
The game is not buggy at all. Well done to the programmers.
Clicking on particular items in your inventory to interact with them was also a nice little twist and I felt that served the overall purpose quite well.
Ultimately "First Escape Games" is a very good description. This is a good little puzzle for people new to the genre who enjoy these kinds of things, or a younger audience not yet able to discern the more challenging games out there.
