@KopanoGS: Thanks a lot for the support!

@Cynicalsandel: Yes! I'll do a demo as soon I finish the Portuguese translation! But it will be released only after the pre-order.
@Yodhe: Well, I hope we can get some exposure, we are trying really hard to send press releases to everyone in the press that we can. And thanks for the advice!
What Happened on Day One & Statistics
We sold today 65 pre-orders (most of them are here from Brazil and friends of ours), for 4.99 each. Fastspring bites off 0.75 of each unit, meaning that we have to pay 48,75 to them. So, the gross profit today is
$275,60 USD. It's not a lot of money, but honestly is more than I expected! I have confidence that the game is actually very good, but it's a pre-order, so people probably like our trailer!
A thing that helped a lot is that we got featured at Kotaku here in Brazil (
link-portuguese only) and since the Brazilian indie industry is very small our game is having some attention.
Only few international sites and blogs are also talking about us, but our focus now is to increse that number, we are still trying to send our PR to some journalists or to other bigger indie game developers (to get some tips and feedback too!). Some journalists are helping a lot, but most of the big indie devs just ignored us

(they are probably very busy, I don't blame them, but that sucks anyway)
This is today's report

Hope it can be of some help
