Tutorial World Layout (Alpha)

Today I designed a simple tutorial world for players to learn basic mechanics. its fairly linear and represents the prologue of my game. of course its not a final version so feedback is appreciated!  

Keys: Self explanatory

Red Cross: HP Upgrades (need 2 for upgrade)

Green: Power-up, e.g higher jumps or more damage

Blue: New Skills

Doors are colored like the area you need to finish to open them. I plan on implementing a little bit backtracking to 100% the game but also a handful of back tracking passages story wise.
