Yeah, Wikkler, in all of the Papa games (except I think Pizzeria), waiting score drops more rapidly as time goes by; it's part of why Posters and Furniture are so important.
The ending is very anti-climactic. Just a screen with a bunch of phrases about how great I am? It's better than "Conglaturations" but I was really hoping for something more. 4/5, though; great gameplay.
The accessories are a nice touch, and I much prefer this Skill Tree interface to the previous ones. The game seems to move a little more quickly too; no more of that ridiculous summon everything one by one. But overall, it's really just more of the same. It needs more customization than it has, I think, to really be great. 4/5.
Holy cow, most of the secondary objectives are really tough. I wish I could just heal my castle back to max to get the "no damage", hehe. Excellent work.
