It's a good point you're raising, I tried keeping it lowest 720p monitors. What else I've learned from the screen size feedback is to handle pointer input from outside the game canvas, or as some suggested make the game canvas larger for non-mobile browsers (to receive mouse input) and center it. The comunity has great ideas to share. I would be also interested in finding out what you guys think the best non-ads driven monetization technique would be? If most of the player base would donate a few cents it would cover for the assets and dev time. Maybe later on if Web Monetization catches up :)
