The game is awsome, and... here are some "cheats":
In the tutorial, you can get the Medals:
"My Up key is Jammed", just standing still.
"Leap, Kangaro", by jumping 50 times (I did it on part 3).
"That was usefull", press 'K' and done the movement (15 times) on the second part.
In the Game, you can jump outside the tetris plataform, came back, use the 'J' and get near again, and press 'K' you can came back from certain death (just don't go too far away, ok?)
NEVER trust the ground '-' (you can be really unlucky, like me ^^) try to keep above the normal line, It's funny to try 'not fall' and you will not be squished.
;P Good Luck guys, and GREAT GAME!! 10/10 5/5
