Dang this is actually so good!! The whole game feels complete and polished. I love how you gradually add mechanics. The difficulty curve is very well-balanced in my opinion. I slightly prefer the checkpoints to be a little more forgiving, since I kept retrying the same sections again and again, but that's a minor issue. Also the books were a bit frustrating to get, but I eventually got consistent with it. The mechanic of telekenesis is also very clever and feels great. Nice music too! Honestly one of the best SGD games I've ever seen.
