Not too complex but definitely catchy! Shifts up nicely after the third second mark, less notably but also suitably around the ten second one, and ends with a creative little off beat hit...
It is a little simple, beat and synth, good rhythm but not really a full-fledged track IMO. Would be cool if you could transform it further. Feel like it'd work well for a comedy sketch or similar as is otherwise, without words, one that builds towards a punchline and then... all good. Good length for that kind of material.
Really is catchy too... nice work.
