I liked the game, definatly think this game could go places and would like to see it go there :)

few things i noticed:

Turrets were a bit pain to place as i was getting stopped by them all the time when trying to place a nice "lane", maybe remove collision for player or add a aim so you can strafe but place them to the side

Base should probably not allow player inside? i was able to place turrets inside base which seems to break pathfinding for me

Adding a path visually by either a line being rendered or in texture on ground

i liked that the player and turrets had HP and the ragdoll of the enemies.

would have been nice if there was a wave-counter and a bit more TD like on the spawning approach?

more turret types would have been awesome!

Interesting .... at least even without resolution controls the UI stayed on screen :D Surprised how well it ran, until it eventually doesn't with too many turrets and enemies :D

Very beautiful game. kept fading to black after afew and wouldnt do anything after that UI was still there and changing number on base hit points.
