Looks nice. I was excited to give it a try. I'm on my company laptop, however, and the screen is only 768 tall. I had no way to view the entire environment which made the game quite challenging.

This is a big feature request, but honestly window sizing/scaling is something you want to handle early rather than late.

Or, you may just want to throw an error page up if people don't have large enough resolution capabilities.

Good luck!
