You are the square. Press space to flip the square to the other side of the line. Press the up arrow to jump. Dodge the red triangles (some do not let you pass).
Created by me. v1.1 -simplified some scripts -added "try again" option -Fixed jumping spin v1.2 -some bugs fixed v2.0 -sooo many bugs and glitches fixed (It took a long time) -cleaned scripts and deleted unnecessary sprite -used "make a block" to minimize script and have smoother performance.
