I don't know if it was because of lag or not, but the intro cutscene felt really slow, so after a couple minutes I clicked skip. At that point it took a minute to load, resulting in the page complaining about being unresponsive. For the gameplay itself, I had issues with the floor just being too dark, so I couldn't tell where there was floor and where there wasn't unless there was a grey pillar nearby. The light colors chosen for the game page really don't help with that. I stopped at the second key, because I ended up repeatedly having to get Gigi back from the checkpoint and then Cecilia's throw didn't even seem to work consistently.
