No Scripting Needed

Limit X Scroll

Shows off the new parameters on the Limit X Scroll event.

Multiple Exits

Beating a level can send the player to different next levels, instead of only ever the same level in a linear order. This lets you make branching episodes or even open worlds.

Pit Level Example

One of JJ2+'s simplest, most versatile features: instant-death pits.

Scripting Examples

(Many of these levels were made when scripting was first added to JJ2+, so the same few features appear a lot, while newer features like network code or ingame instructions aren't represented. Please let us know if there's anything you want to see a level for, and also check out the Snippets database.)

32-Bit Graphics

Overview of JJ2+'s 32-bit graphics: palette-independent tiles and sprites that support alpha channels.

Battle 1 Plus

Edits the generic Battle Game multiplayer map to show some very easy JJ2+ effects: palette changing, music changing, antigravity, and looping layouts.
