Yep, I've already checked the license, it makes a lot of sense, and a lot of parts I like especially (like being especially hostile towards micro-transactions in games - thanks a lot for making effort to reduce amount of that stuff in our world), but unfortunately stance towards redistributing free assets as part of open-source projects wasn't 100% clear. Although it is a bit sad for me, because it makes their usage in open-source a bit clumsier, I do get that you probably want to have a tighter control over distribution, and I respect your right for this. Maybe it makes sense to update license to make it a bit more explicit, in particular the phrase "You may NOT resell or redistribute (either commercially or freely) my assets (including free ones) for other people to make their own products".
Thanks again for swift response, and of course for tons of great assets you made, recently spent about 200 euro on them, don't have a slightest regret!
