Ran around on this earlier. Lovin' it for the most part but I ran into 2 overarching issues that were holding me back. 1) I'm sure you know about this one but the framerate when looking towards Mid from any angle is commanding and completely steals all attention. Its either looks or frames but in this case the looks are killing the framerate and I think it's because of the many objects detailing the center of the map. 2) Some areas feel a little big, while others feel tiny. For example, snipe tower and blue room feel like they got stretched out big time, while the jump between blue and gold feels miniscule compared to the original. Again the map looks incredible but the gameplay may be hindered by the aforesaid issues.
This is probably the best looking remake of Guardian I've seen so far. Just try and straighten out the performance issues in some areas like @HeX Reapers said and you'll be golden!
