Since this is a community made mod, not a game made by a company, you really can't complain about it much. But honestly, the team behind Echoes, knew what they were doing and are to be praised, especially the level designers. The level design is like nothing I've seen in any hl mod, really pushing the limits. The rig animation is also really impressive when you notice it and the re-use of cut-content was very cool. The plot is, there, nothing to write home about really, it's there and more for people who are invested in the hl universe than anything.
