Very nice use of the theme, enjoyed the breaking down of reality.
First play through I thought something was bugged and stop before the double jump because I was missing way too many bananas. After restarting I felt it was wrong to have to back track to the dash upgrade so I used a trick I found to wall jump up a little and grab that upgrade first.
Found the UI only accounted for having the double jump first so it said double jump instead of dash.
Pretty fun with a touch of difficulty near the end, with more levels and polished movement and visuals I can see my self playing this game through.
