Thanks man, and happy to support such cool assets being released for free! I might reach out sometime soon for some asset talk.
Just played your latest update - it's very very cool. Really enjoyed it and it was fun for me to see my models in your game. Drop me a message if you'd like to collaborate on some more assets for your project. I was working on a little casual plane game a while back and I'm going to be uploading all the assets over time to here but if you need any specific let me know
