It's great to see CO2 come to Steam, and I think it will do well there.
But to avoid the inevitable storm of support requests on the forums there, I think something needs to be done about the UI which is starting to really show its age. To avoid bad reviews something has to be done to remedy some of the issues and modernize it.
- In high resolutions like 4K everything apart from the map is ridiculously small. I play in 2560 x 1440 and even there some things are way too small, while others like the messages text is large.
- Using Windows DPI Scaling set to 150%, and I get issues with text overflowing UI borders, creating a mess, and some of the text still extremely small while other seems to scale.
- Trying to run in lower resolutions the UI elements just turn black and everything is blurry since I have to run in non-native resolutions...
In fact these things are reasons why I don't play CO2 as much as I'd like to, even though I love it.
In addition, the Steam user base are very quick to give bad reviews and ask for refunds, and tend to swamp the community forums with support after release, so it will be very important you guys are active there every day as well.
