Hello everyone, I'm Rei Kagetsuki the creator of the kickstarter. Sorry it took me so long to notice this.
First off I can keep an running total of pledges if everyone from HLP sends me a message after they contribute. Just hit the "Contact Me" link on the right after you contribute and write "HLP", in my kickstarter inbox it will show your message and in the header shows you are a backer and for how much. I'll keep a running total right on the main page for you. It looks like you've all already started accumulating through PayPal but it also looks likes some have contributed directly - the PayPal ammount could go in a lump sum no problem and anyone who has already contributed please contact me with "HLP" as the message and I'll start adding it up.
I'd also love to make an update mentioning the HLP project and how you all want to implement APNG.
I would like to know however what type of port HLP has in mind. I've never done any development on FSO but it looks like it's all C++(98?) which should not be a problem as we aren't using any features that would be incompatible [as long as I'm not mistaken and std vectors are supported]. Do you actually want us to implement the APNG abstraction layer for in-game assets?
Thanks for your interest and hopefully for your support. Having HLP as a model for implementation in [non-web] games will be great!
