The concept in this game of a tower defense where towers are on timers is brilliant, and has a ton of room to be expanded upon. The art style is great and the music/sfx are wonderful (I laughed at the insane amount of reverb on the death screen). It could definitely be made more difficult, such as by making towers cost more (or enemies give less coins), or make the lily repair cost increase exponentially to some degree. Also tougher enemies. Still, I really like this one!
