Secret Medal is Die 50 Times.

The game is pretty boring, similar to the 12 other platformers that have come out lately and require a certain number of deaths for medals.

Deaths is 4Bytes*1.  Search for it 4 times or so, dying to increase the value, play through the game, change it to 0 before touching the flag.  Flawless Victory.

The 8 coins are attainable with either character, I really don't wanna write a walkthrough though.

For the one where you can't jump high enough to reach it, just fall into the pit, it teleports you to the sky. The rest are just buggy hitboxes and double jumping.
