So, I finally got the emulator to work. But, the Ren'py software was "made for an older version", says Google Play. Well, hope it's good. Who am I kidding, I know it is. Well, good luck on the progress, Kal!
Oof, I sympathize. My computer's humming the last hurrah of an 8-year death march. Struggling to play modern games through most of the last 2. I'm just glad to have experienced Ultrakill and as many games like yours
