thanks!
I wish I could list them for cheaper but I'm posting on a few markets and one of them has rules about selling significantly cheaper elsewhere. They have a minimum price of $5 over there so I decided to put it at $5 here and add an 80% discount for the first few days before I upload it to the other market. Hopefully if people want it they can snag it while it's $0.99
I have a pack of 729 assorted icons in a similar style too if you're interested. It has some different gems included as well, just nothing like this selection. I have a small free-pack of similar assets too.
I wrote some code to turn the gems into square icons and make tilesets but I also wrote some code to turn them into pixel art. It's not perfect yet but hopefully it wont be too long before I'll have some pixel art packs to put out as well.
