Full Disclosure: I have an entry in the Jam.
Spirit and essence of Harold: Harold is front and center
Fun: Interesting story but without many opportunities for player choice and frequent narrator control over Harold, it felt like a bit like a visual novel.
Creativity: Numerous good ideas executed in this game. Lots of custom art and music. Great use of plugins.
General Comments: I played the Game Jam version which may explain why the conclusion of the story was abrupt. Many of the large maps felt empty. Without a border, it was never clear where there were exits to another map and where there were dead ends.
FYI, you can significantly reduce the size of the .zip file by selecting 'Exclude unused files' during deployment. This will ensure only files used within the game are copied into the deployment folder (Most of the file size comes from the very full BGM folder)
