A very interesting RTS style game with some wave defense thrown in there and a interesting art style using primitives and such. It was really cool seeing the enemies because they were all very distinct from each other and had some interesting differing attacks etc.
Though I do have to say it didn't really feel like waves, since the timer was always ticking without me really having to pay attention or even noticing it just being at the top of the screen. There was also never really a call out to a wave starting or any really introduction to the difference between units.
There were also definitely some issues with pathfinding, mainly the dynamic pathfinding (which I mentioned). As well as an issue with the "minions" and also enemies, pathfinding through each other, rather than around or with each other. Which lead to a lot weirdness when they were attacking etc..
