Loving the game and this is right up my alley, but there is one problem I've come across- my GPU's cooling can't keep up (shoots up to 90 C within minutes), which doesn't make sense as it's able to handle things that should have a higher demand. Might be because I'm on Linux and am running this with Wine because there's no Linux port, but it's still worth noting just in case, especially since other games aren't having this issue with Wine on my laptop.
Edit: Interestingly, it drops down to 70 C after the first 10 minutes or so.
