Woo-Hoo! I've finished my first big game! Use arrow keys or WSAD to move. All special things are explained in game. If you get stuck in a wall, which occasionally occurs, press up arrow/w and press the direction that you need to go to get out (up arrow and left arrow or w and a to move to the left). Enjoy the twenty-three levels and the boss level! This game was mostly done in bitmap, until I finally noticed the quality of vector, so I redid some things. Currently, half the game is in bitmap, and the other half is in vector. And no, level seven is not glitched. That exploit is MEANT to be there, otherwise the level would be impossible. (If you haven't played yet, you'll see what I mean.)
Credits are in game. IMPORTANT HINT: For the later levels, glitching is the only way to succeed... Oh, and I finally got rid of the terrible level six that nobody liked. It's now another level you won't like. Thanks for the suggestion, @MeatBoy7 and @FratilaCAT!
