Arrow keys to move. And space to shoot at the boss level. I tested it and it is all possible. Press N key to be the normal costume and P to be the pug. PLS COMMENT. Also if you are confused about which way to go on the 1st 3 levels then press the 's' key. And then press 'h' for it to disappear. You can also wall jump.
In two days the two-year event of this game is complete! To celebrate this, I have added level 14, bounce pads, and fixed some bugged spots on levels, level 15 coming out soon! Also, I have cleared all levels and finished the game multiple times so it is 100% possible. (: Also on level 7 touch the blue bar to move the red blocker. 2 MORE LEVELS HAVE BEEN ADDED AS 4/15/22+bug update and level improvement.
