I love this game, true free game, and it runs very well in my "potato" laptop. Core i3-7020U, Intel Graphics HD620, 4GB RAM DDR4-2133MHz, Windows 10 Home 64 bit and a traditional (and very slow) Hard Disk Toshiba. I can recommend for several PCs older or weaker than my laptop, unless your PC is a "very-true-potato". I am waiting for Steam release and I also play it in my smartphone Android 11, without ads, nor in-app purchases.
