This was fun! I enjoyed your take on puzzle platforming. It's a genre I often do not enjoy so, that I did enjoy this says something!
The graphics are good. Well drawn, easy to read. Your palette is great, the golden hues really match the vibe of the game and the jam.
Soundtrack is good, I enjoyed it. My only complaint here is that moving through levels quickly meant I really only heard the opening few notes. To hear the whole song I had to slow down for a moment.
Gameboy soul? You got it.
Quirkiness: Your midas touch interpretation feels pretty danged quirky to me!
Theme interpretation: There is gold, it is old. BAM!
