I second the Ragnarok Online vibes, it immediately came to my mind within the first few seconds. Turns out it was Maple Story, close enough! Honestly it's a really well made soundtrack, it filled me with the sense of adventure you feel at the start of an MMO. The tempo changes were really nice, it injected more humanized touch and created some nice contrast between the more electronic sections. Don't have any complaints, you nailed it!
