For those of you who might be getting a virus warning or a safety popup of some kind from the settings.exe/s19345.exe files, this is because the publisher/developer did not pay for a digitally signed certificate for their executable.

In Windows, if you look at the properties of steam.exe (c:\Program Files (x86)\Steam\steam.exe) you'll note a "digital signature" tab. These signatures are actually quite expensive and there's a whole reputation system. It's to try and reign in malicious software.

If you look at the properties of settings.exe/s19345.exe you'll note no such signature tab. This is why you're getting the warning: the OS, virus scanners and/or security suites can't verify the exe so it's trying to protect you. From yourself. It does not mean it's more likely to be malicious in some way. Personally I would consider Steam to be the verification of a non-malicious file, but that's just me.

As for the actual game it's exactly what I was expecting: an arcade game from the '90s. It also seems like the typical PC port of an arcade game from the '90s in that there's no in-game settings menu, no menu item to exit the game and it doesn't auto-pick up a controller once the game is running. Must plug every thing in before launching. Being from the '90s might explain the lack of digital signature. There are also very limited options on resolutions. I ended up playing in 1920x1080 window, which is fine. This is probably a port of the PS1 version released (the directory structure of the game folder would support this). I kind of want to compare the two, now.

I don't think I played the original arcade game for comparison. I can say the controls are very tight and the sounds and music are exactly what I would hope for. And I think I like the mocking of players who choose an easy difficulty. Even I didn't choose the "monkey" difficulty. I'll stick to "child", thank you.
