Use the arrow keys to move, space or click to throw hairballs(hairballs do damage to enemies). Avoid the spikes, collect coins, jump on top of the dogs and avoid water/holes. Don't let the dogs hit you unless you are on top. Hit the catnip(green plant) to speed up(still working it out). The door at the end of a level makes you go to the next level. Somewhere in the level, there will be a lever. Hit it to unlock the door. The switch on level 5 destroys the black blocks and lets you access the boss. The star at the beginning of a level takes you back to the previous level. If you want to stay on your current level then avoid the star at the beginning. You have 3 lives. Holes/water automatically restart the level but spikes and dogs just make you lose one life. If you lose 3 lives then game over. Level 5 is special. Try not to fall into water and don't hit spikes. Rocks crumble. Not all of the blocks are solid so be careful. At the end there is a boss. Defeat the boss to win. If you defeat the boss, touch the blocks at the end of the screen to restart the game(still working on it). Press enter to pause and resume the game. Look for hidden passages! Still working out some things.
