As far as i'm concrned, "Lonely Island" is a fan made map. According to this, that very fan could made (convert) his map for wormux. This looks simple. I doubt it's about stealing resources.

It's nowhere like about stealing anything. Our maps are distributed freely under the terms of free license, so there's nothing special for maps to appear in another FOSS game. Both projects could benefit from sharing maps, sounds, ideas and whatever else. Best wishes to Wormux team!

I didn't say steal. All I meant is that Wormux likes our maps (I mean, who wouldn't?).

Well... I performed some investigation, and that's what I found:
[o]

Lonely Island map was added to Wormux in April,16 (wormux r4192)

Lonely Island map was added to Hedgewars in July, 5 (hedgewars r1072)

[*]Lonely Island was updated in Wormux on July, 12 (r4708) - most probably it's just the same map in hedgewars style[/o]

Ahh, I see. What about the cheese map?

The cheese map was directly converted from Wormux by me

OK. Perhaps Tiyuri should make it in hedgewars style. It looks nice, but has gradients.

Basically Alzen drew lonely island for Wormux, and wanted to convert it to Hedgewars, but I decided it was rubbish, and told him how to redraw half of it. Which he did, and then changed the wormux map also.

Oh I see. I wish Alzen best luck with the Wormux project.
