Thanks, zooming out on my browser worked.
Interesting idea, but it needs more ways to challenge the player. The biggest problem is the existence of a no damage tower (elf+food), as it's so good that it makes everything else irrelevant. You can solve this in many ways - making sure every tower does damage, always adding a random tower each round, making it rarer... etc. I think the game has potential though and hope you continue to work on it!
