Blast from the past
Really like the touches. It gave me alot of memories of my youth, which any game that can do that is special. I think mechanically, it felt good on most of the levels. The zelda level in particular was alot of fun and i hate the zelda series and never bought (probably never will) any games of that franchise. The puzzle of it wasnt overly difficult or tedious, there was enough paths to feel satisfying. Boss fight was fun too.
The variety of medals also was cool, it matches the sillyness and the abundance of the game so i think having alot of medals works.
I found the balloon fight level to be kind of frusterating. I think on a gamepad it'd probably feel better. The tension of the gravity and the slowness of a keypress made abobo feel unfairly heavy sometimes particularly if you accidentally miss popping a balloon. you just plummet like a rock and have little to no chance of saving yourself from the heavy pull of gravity.
Also i found the logo intro at the beginning to be a little too long.
Good work. Loved his son's baby blue eyes.
