It has a bit of a 90s console feel with the graphical style and low-detail modeling, but is also a bit MSPaint-ish, which makes it feel almost like an early 2000s fangame. Either way, it's a cool aesthetic, and the way it's used fits the jam.
The concept is fascinating and definitely fits both the theme and modifier, however it definitely feels underutilized in its current state. It pretty much functions as a somewhat janky platformer with contextual actions.
I was not expecting the ending, but I did read the explanation. Unfortunately that happens during jams some time. The concept is certainly interesting enough that I'd like to see it continued, though!
