Hey dev team,
Noticed some time ago that this page doesn't have a spec sheet. I know that most itch games don't have one, but considering that this is a game made in UE4, I personally think it's pretty convenient to have one. So, I took a bit of time to experiment around with settings and specs and made a (in my opinion) pretty accurate sheet for the minimum requirements! (720p, 60fps* @ lowest settings)
Processor: Intel Core i3, i5, i7 2.8GHz Processor or better
Memory: 4 GB RAM
Graphics: GTS 450, 2GB VRAM
If I had to guess the recommended or ultra/4k graphics settings, I'd say GTX 750 and 780 Ti respectively and 8GB of RAM, but I can't speak from experience since I don't have those GPUs. :/
Hope I helped!
