I watched someone play it and seemed fun time, but the controls didn't work well for me. Perhaps because my resolution is 1280x720?
Either way, it's a cool game, thanks for the submission!
I tried again and in full screen it works just fine. Window mode though, the selection areas get messed up. Since my resolution is 1280x720, just like the game, the browser's window components reduces it even further
To reproduce it try running the game and reducing the window size. To fix it I think you have to set up the window display in the project settings. Perhaps mark Resizable, and change Aspect to Keep and Mode to canvas_items
