Ah! .. I remember this game now.. I recognise the screenshot of him in train carriage.
I first tried this late 2019 and if I'm not mistaken; it's over 4GB.
It seemed like for 2 minutes there was just a black screen, AND THEN the picture started fading in to him in carriage, but the framerate was 1 per 10 seconds.
I posted about it and someone replied - "Yeah, he had it almost finished but then chose to do the whole lot in 3D which totally fucked up the hardwiring thus is now looking to do a complete rebuild" (something along those lines).
So I think it would be worthwhile to upload an older version b4 the Dev put his 3D dick into it and fucked it big time.
