left and right arrow keys to go left and right, up arrow key to go up. on levels 1 and 2 you have to jump under the star box to get the key, for level 1 you have to get the key to the left side and for level 2 you have to get the key to the right side, for the boss level/level 3 you have to keep on touching the boss to win, you can see the boss health and the timer to defeat the boss, the animations might be slow, comment if there is any bugs.
Comment if you want any changes or if there are bugs(glitches). That is all. To see all the instructions you have to scroll down. I dont know if this supports mobile so it might not. My first good project :)
