unfortunately i cant i use unreal and it doesn't have browser support and even if its miraculously possible somehow its going to run like shit + but i see alot of itch pc games with so many downloads this is when i get really sad about this.
A very teeny tiny percent of games gets huge downloads. the vast majority get 5< in their lifetime. Itch is a much different ecosystem than something like steam. people dont come here to download as much. I only play browser games here. all my other games are in my steam library.
