This is really, really fun, probably the game with the most potential. I really encourage you to keep working on it because with a few added things, it could do really, really well. I feellike you should be able to have multiple paths and I also found that sometimes, even though the enemy is very close/in the direction the fighter is facing, they won't attack for some reason, that could also get worked on. Still, I had a lot of fun playing it, and I don't usually like tower defense games.
