I just want to let you know that personally I don't aim to try to get highest on some donator's list. If Humble Bundle inc doesn't want(they complain about "legally dubious" and are with EFF's standpoint) my Bitcoins I'll give them to the developers of games
I liked for each bundle. Humble Bundle inc. gets my 0.01 USD. AA one of the Eufloria(who's now busy with porting it to Android) devs showed interest in trying Bitcoin out, and recently I'm contacting the devs of Cave Story+.
Though if you really want to try to get highest on Humble Bundle Inc's donators list I wish you the best of luck!
