Yes, I am to be honest. I am in mid production of a (sidescroller, similar to risk of rain) rouge lite (modern with guns) and in need of detailed 64x64 or higher icons. There are tons of icon sets here on itch.io already but all with different styles and honestly too low 32x32 or smaller is too crummy. Also most are limited to one theme (crystals, or flowers) but not in a general purpose way that all games have ( a hp heart, a clock for cooldown etc. ). I would even promote you on my small yt channel if you got a really good selection going on or order buy if you are into that.
This is what most developers need more or less:
Skills in upgrade tree: (health, armor, crit, critchance, super crit, food, mana, subweapon, etc. )
In game temporary passives: health, damages (bleed, burn, freeze, slow etc.), armor, reload, cooldown, special effects, buffs, curses
