itch.io

I had the same problem. For me it was because I extracted the game files from the zip.file using only windows tool. It seems to start now after I extracted the files again with the 7zip tool instead. I was a little lazy when I read the instructions on this page.

I'm having the same problem on my new pc, I hope they make one that works with regular extraction soon, since the extract on my pc can extract from any time of file just fine normally

U have to unzip the game, and then before u start the "Small Complex.exe" u have to go into "data" folder and double click the "bakinplayer.exe" and then confirm the windows "unsafe exe" window with yes, and then u can open the game exe file, and wait for a bit.
