Awesome! Honored that this was your first card game! Do be sure to check out the other excellent games that came before because there have been some absolute gems in this genre!
I'm sooooo sorry for the headaches with hitting ESC. I (Ben) have personally totally also run into this and it's an awful feeling losing a run because of it. We will 100% be adding a little "are you sure you want to quit" pop up to save people from this in the future.
The double bashing on doors is also an issue we're aware of, and it will also be fixed in our next update. Thanks for letting us know and helping us make this the best game we can!
