That doesn't sound quite right to me, I wonder why... :P
Listen to it a little bit longer
Celeste has a great chip-tune soundtrack, and the B-side versions are even better. It's definitely on the slower/lo-fi side compared to Undertale though.
Almost all the Street Fighter games had amazing soundtracks. SF2 being the standard.
Streets of Rage 2 is considered one of the best OSTs of its console generation. "Go Straight" still holds up.
Chrono Trigger is still the greatest of all time for me, though it is a much more orchestrated affair in most instances.
Based on your descriptions I'd say that the soundtrack from the Scott Pilgrim beat-em-up game from a few years ago is what you want. The whole thing was done by Anamanaguchi. Just go listen to "Another Winter" and see if that fits your tastes.
In this thread you can, as by the OP I assume that's not the type of music they are after. Octopath has orchestral soundtrack, not bleeps and bloops.
