Overall I really like the theme, and the play-ability of the game! Great job!
Small little thing but I did notice the tutorial part where the shoot robot portion have the words come up only after i went towards past the boxes (i already shoot the boxes and robot down). maybe have it shows up a little sooner, since I think it doesn't hurt for player to know it sooner.
Another thing is animation sometimes doesn't have the player going towards the right direction, but i think it was fine (only mid air sometimes).
One thing I wish is for the platforms to feel a little more constrain to player's ability on wall-jump/double jump. Like limiting the amount of wall jump the player have and make a little bit of platform puzzle for players, so it isn't just a spam of "space" and be able to go through everything.
Not bad, and I would love to see more :) Cheers!
