Alright just checked stuff out, seems way better than before even if i feel some stuff could still be free, in terms of requests could you release some free characters or templates for them? since at the moment all characters are locked behind paywalls, so if someone use those tilesets for free they will need to make their own characters from scratch.
In terms of sending keys via email, will you allow us to use content obtained via those email keys for public games that are free or non-commercial? my game at the moment is free and is more a experiment rather than 100% confirmed normal game but i do plan posting it on public so would be useful to know that, i don't want to get those keys use the paid content and post my free game on public and then get told i'm doing piracy or something and should have bought the tilesets with those keys just being to test stuff out or something.
Yeah no worries about licences, you'll be fine with download keys. I'll probably make the free version "non-commercial only" but the download key grants you access to the full version anyway.
Regarding Characters : the characters pack with be converted to free + paid version this week (I hope this wednesday, but maybe this weekend). I'll let you know when it's done either way.
