I wanted to check out this game, but when I try to launch it all I get is a small white window poping up for few seconds before the game closes itself. I'm not sure if you still work on the game, but I'd like to give it a try, so if anyone knows what might be going on I'd be really thankful for your help.

I solved it. In case anyone of you fine people for some stupid reason did the same thing as me and bought an analog keyboard like razer huntsman, which can simulate gamepad input, renpay games may decide to just not boot up. In such situation you have to hold shift while launching the game so you're brought to this renpay menu, there you have to disable gamepad input entirely. For some reason, even when I did not use this feature actively, renpay would just pick it up and halt the game from running, I have no idea why, but that's how it is I guess. I hope it's helpful.
