Overall it's an excellent use of theme as well as OGA resources.
I'm not gonna lie, I found the controls a bit difficult to learn and took me a while to understand that I can use the mouse. Can you include the controls description on the game page for players like me?
Also it would be useful to know that now you are a bit too far from the link by maybe turning the link red? This would not jar the player into just draining off to death lol!
Thanks for sharing this, it's an nice take on the theme.
