Skill Levels
The game and each individual level can be played at one out of four skill levels: Easy, Normal, Insane, and Psychotic. Each of the first three presents an increasingly difficult challenge. Psychotic Mode, the final skill level, is the most difficult and only allows a single life. Completing all four will unlock a 'true ending' for the story.
Weapons
During levels, the player may obtain different weapons by shooting a coloured box with a weapon. The weapon will be utilised by the respective hand that shot the box.
Scoring
In each playthrough, the player will be awarded scores for shooting certain targets and enemies. At the end of each level, the player is then given a rating and score breakdown and is also rewarded with points for accuracy and for every time the player achieves a multi-kill. Hitting valid targets adds a level to a multiplier, which can rise up to a maximum of 8x. The multiplier drops if the player stops shooting, and resets if the player takes damage. The scores the player gets are stored in an online leaderboard.
Secrets
A number of hidden clown collectibles and a single mystery item can be found in each level. The single mystery item provides a short story sequence. The game rewards the player points for finding them.
Routes
There are a number of branching routes to be taken, and some of these are hidden. Each alternative route will present the player with hidden secrets, more scoring objects, or additional information to the world.
