I love this style, hyper light drifter is what got me into games so I'll always love that style. However I do feel like if I use this for most of a game I'll end up not having enough. Specifically larger space filling foreground things like trees, totem poles or bamboo esque plants, something to complete the large alien flora side of things.
I'm considering buying already but a few more of those things would make it an easy choice. I'm sure you're busy though, I know it's old :p Great pack, either way. Love the colors
