Nice! I think this game has a cool approach to the tower defence genre by having the player set the path for the waves beforehand and have that pathing also influence initial cost. That's a very innovative idea and definitely one that could sustain an entire tower defence series of games. I found it very addictive! The towers have a nice balance between the pea shooters, snipers and flamethrowers, as do the enemies, which have their own amusingly varied approach. I think it's really tricky to balance a TD game and found at times that the waves were just too much even with the economy that scales over time. Maybe upgradeable towers could be a way of players thinking about how to use their best spots most efficiently? Enjoyed this a lot from start to finish. Great work!
