Super Jimbo Quest concept art 2! (Patreon)

 I know at least one element I want in the game is picking up powerups to get beefier - that'll be the first "transformation" element I put in and base the first stage around. You pick up protein shakes, hunks of meat, etc to bulk up, and if you take damage you shrink down a level. There'll be enemies and barriers to punch through, and a boss fight that'll be easier if you're beefier. 

Later on I'll make additional levels with other expansion/tf themes, either as additional content for this game or as level design material for a sequel.
