I really like the overall design and quality of the pixel art UI pack — it's clear a lot of work.
Edit: I was able to change the colors using aseprite, thank you very much.
Hey, thanks for the kind words and the helpful criticism.
The white versions of all the sprites are included to allow recoloring them in-engine. Additionally, it was made in Aseprite, which allows you to replace colors across all frames and layers in a sprite to easily change them using the color replace feature. You can select all frames then press Shift + R, to replace one color with another. I hope this is helpful.
If you would like a refund, please let me know and I’d be happy to help with that too.
Thanks again.
