See title. Displays white empty window and closes itself after a while. No log found. Same happens with the Steam version.

Config: AMD Ryzen 5 1600, Radeon HD 7800, 16GB RAM, Win10.

the game won't start, don't get a screen of any kind, white or not.

it just doesn't run at all.

Same issue, no screen or any sign of activity. It's a shame, I was looking forward to a functional modern source port of this.

Full specs, os version, and dxdiag log would help us to find the issue

I'm using Windows 10 Pro, version 21H2. compilation 19044.2006/

For some reason, I couldn't create a new topic. I have crashes after playing for some time:
I've played in 1440p, shading quality: 3. Id tried with DX12 and Vulkan, and the result is the same: crashes after some time (around 15 minutes maybe). I could finish the first level the second time I started the game and it crashed on the second level.

I found this in the Windows Event Viewer. I'm not sure it's helpful but looks like referencing to unassigned memory:

I'm not 100% sure but it looks like leaving shading quality on 2 solves the problem. At least I was able to finish the second level without problems. It was around 20 minutes max because there is no level 3 so couldn't test more.

So I've found a fix for this on the Steam forums for the game:
