Cool game, I wish there was a way to speed up the gameplay because sometimes you just wait for enemies to pass the level, also the library looks huge some props like the chair make me feel really small in the room which is not necessarily bad but just to let you know, the towers were sometime locking to different enemies and resetting their cooldown shooting timer which made them not shoot at all and fast enemies were just passing by, too bad there is no sounds or skybox because it would add a lot to what is already a good game
