Insanity City

Insanity City is the first level of Patrick's Adventure.

Level design
Patrick washes up on the shores of Insanity City after plunging from Dr. Scientist's laboratory. Patrick performs a single Belly Blast, informing the player of his main attack, and the level begins. The rocky path is relatively simple and introduces the player to Fish Fruits (Acting as a coin in a Mario game would. Collecting 100 gives Patrick an extra life), crabs, extra lives, bottomless pits, and iron boxes.

In the middle of the level the player discovers a checkpoint, giving them Apples, a ghost assistant that lets Patrick takes a hit. After that the rocky path forks in two. The left path contains Fish Fruits, but the right contains a box bridge - the challenge of the level. There are no crates, but their outline can be seen, and the only way to make them appear is to hit a small button with a ! on it. After the path joins back into one, the exit can be seen.

Gem
Gems are collected by smashing all the boxes in a level and/or not losing a life. There are not many boxes in this level, so the gem for this level is fairly easy to get (also because it does not require a colored gem).
