The game system is not original. It's almost same as Sally's series. Oh well, I don't care. New time management games are seldomly published... Time doesn't pass while you're playing minigames. Perfect score is achieved by serving all 'possible' customers while making all of them have 5-star. However, some levels are impossible to earn Perfect rating without +1 star upgrades. (In some levels undeads come with only 2 stars. Also, there aren't enough stations to increase hearts in early levels) In early levels, a zombie with suits may come in. Hit the head to hire them as zombie butlers. Orange bottle freezes star decrement of all undeads in the shop. Blue bottle gives out a star to all undeads in the shop. Red pill knocks down all undeads walking around. (You don't need the pill if you want to beat the level by Perfect Score) Putting undeads in the casket consecutively gives combo bonus. (+10$) Basic strategy is the same in all levels. However, there's no way to increase number of stars except minigames and +1 stations. So, serving speed is really important. While not using the orange bottle, I sealed the casket when there were 3~4 undeads waiting for it. Use the orange bottle when there are 2~3 undeads left to come in the shop. I used blue bottle when there was an undead in the casket with only 4 stars. Graveyard bonus games? Oh well, they are bonus games. The last bonus game is really good to achieve 'Brain Buster' thing. (Smashing zombies is very easy in this bonus level)
