MacLeod's description:

Genre: Electronica
Length: 2:52
Instruments: Synths
Tempo: 134

A sort of square swing piece using very simple synths (but highly post-processed). It just makes you want to explore that dungeon, doesn't it!? 8bit Dungeon Level is similar but slower. ISRC: USUAN1200067 029 Action, Dark, Humorous 2012
