Most of the instructions are in-game. But in the harder levels, they can get VERY hard, so watch out for hidden things such as a channel under the ground (a slightly lighter color than black), little specks of stuff you can go on, and words that you can walk on. Don't click up arrow when you swim (more instructions about that below). In level 7, you might experience a glitch. I am working to fix it. You will know what it is when you experience it. And in level 18, what you think may be a glitch may not be a glitch but a path to the finish [of the level]. If you experience the Hitbox Bug, some levels will be impossible. The Hitbox Bug is when only the center of the sprite reacts with stuff around it and you will know it occurs on your device if the cat always sinks into the ground (you'd notice it). If you get stuck, click R to restart the level. And when you swim, there is no need to click up arrow unless you want to go up [a LOT and VERY QUICKLY]. If you click up arrow, the water will bounce you up pretty high. In level 16, it tells you to click the UP ARROW so that you don't fall off the map. But at the end of the level, DON'T click the up arrow so that you won't sink down far enough to tough the red at the end. In other words, don't click up arrow when you swim. So go on and play the game! Quit reading these tedious instructions!
This is a work-in-progress.
