All these levels are possible to pass, I even tried it out myself! P.S: The rain level is passable, you can go through the dark teal rain. Scroll down for glitches. INSTRUCTIONS: Use arrow keys: Up, Left and Right. Press R to restart (also press R if there is a glitch.) Don't touch the water or else Rocksannna will drown! To wall jump, press the up arrow and the left/right arrow next to the wall. GLITCHES: When your next to a platform and you press the right/left arrow next to it, you will find Rocksanna the rock sinking. If this happens to you, press the letter R on your keyboard to restart the level. At the ending, you can move Rocksanna around but she isn't meant to move around at the ending. You can find her sinking to the bottom so try not to move the arrow keys at the end. You cannot restart the ending scene.
Credits to all the people who made platform games and wall jumping engines, I also give credits to people who made projects of how to get your sprite to move around in platform games.
