bustabit now has a csgo skins version at csgocrash.com.
though about doing it long time ago and finally someone made it.
p.s. are they aligned with your open source "rules"?
They actually bought a copy of the source:
bustabit.com/license.txt
and seem to be doing a lot better than original! Kind of amazing really, I'm glad for their success.
(It's been a while since a version of bustabit was released under an opensource license, but any copied used with that has the condition it must stay under the same AGPL license)
