Jazz Jackrabbit 2 Online

What started as a restoration project bloated up to a culmination of all JJ2 versions of Diamondus that came before. This huge tileset conversion allows you not only to use the retail and beta Diamondus tiles without borrowing them from other tilesets with AS/MLLE, but also to seamlessly connect them as you please. Completely new stuff is added too to give more customizability, more use for certain types of tiles, and support for more tile-based events (ie. sucker tubes, water blocks). 3870 tiles, 13 palettes.

Because there is so much added, the difficulty ceiling of putting the tileset to good use is inexorably significantly increased. Though I tried to make the layout logical, while also making it (mostly) backwards compatible so that it’s more inviting, over time as I made fixes and necessary additions it became really hard to keep such a huge thing completely in order. Hopefully, just as with the original JJ2 tilesets, even some mess here and there can be overcome with muscle memory.

While the tileset doesn’t require JJ2+ to be used effectively – in fact, that’s probably the main reason why it’s so big and convoluted – the example level requires it. Hence the upload tag.

The example level also doubles as a demo for my SP episode, as it is one of its levels that was really asking for a rework. So, by needing something to show off how to use Diamondus Ultimate, I managed to kill two birds with one stone! All story stuff is removed though.

I really recommend playing on medium or even easy difficulty on your first go, so you can focus on tileset tips it includes – higher difficulties, like in JJ1, have a time limit!

And yes, the winter palette from Pyromanus’ Diamondus Beta is missing. I want to give it some extra attention so it actually looks like winter, and not just light blue summer with the snow event and some questionable color choices. However, I also didn’t want to extend the production time of this upload even longer than it already took. Expect a separate upload sometime later (likely near winter holidays).

[Minor update: level ranking now properly appears immediately as level ends]
[10/02/25 update: updated package with newer versions of Demon Dash libraries and edited script to account for those – now you can download this demo AFTER Jungle Ultimate and not worry about breaking anything if you overwrite files; also changed boss music to be consistent with 2nd demo]
