For some reason I keep getting into these situations where I start playing emotional games in the middle of the night thinking it'll be a quick and easy experience only to find myself completely blown away a few hours later at five in the morning. I think this game in particular benefited a lot from me being in a half-asleep state most of the time. It helped to ease my mind and thoughts into the bizzare dream world while still having a decent understanding of what's going on. I did have to do a second playthrough to actually remember a lot of the minor details though.
Anyways, this game is pretty great. Despite the movement speed being just a tad bit too slow, I was always motivated to keep moving and exploring just to see what kind of unique places and things awaited me. It's a very surreal experience but not too surreal as to be obtuse or completely nonsensical. The music also helped tremendously in keeping me going, especially during the giant maze section which has my personal favorite track. Ollie is adorable and the conversations he has with Jon are even moreso. I'm a real sucker for lighthearted stuff, especially when it's a shining beacon of hope in an otherwise hopeless or depressing setting.
My favorite scene is either Ollie's final intervention with Jon in the sunset area or the game's finale. I think I enjoyed Ollie's last intervention because of how much of a stark contrast it is to Jon's dreams. It's a straightforward, casual conversation with a friend in a gorgeous environment in a game that's otherwise bizzare, depressing, and frightening at times. I definitely enjoyed Ollie's other interventions for similar reasons, but the final one absolutely has the biggest impact for me. The game's finale is also amazing. The visuals, sound, and text combine together to make something that's just screaming with emotion.
