omg i got this like a week before it became paid, might give a donation anyway
That would be wonderful, and much appreciated. Glad that it sounds like you are enjoying the assets in any case :)
Can I still use this (giving credit, of course) in my game even though I got it before it became a paid asset?
Indeed! I run some packages for free either for a limited time or indefinite. If the price were free for a package I made at the time you got it, you just were lucky that you found it while I were running it for free.
Ok, thanks!
