I tried playing the game, and level 2 seems impossible! I could not beat most of the levels here...

The intended solution for level 2 is to disguise yourself as one color and use it to trick the two enemies into fighting each other. Unfortunately there appears to be a bug with the retry button that doesn't properly reset the AI's aggro table which we only discovered after the jam ended :/. As a workaround you can go back to level select and back into the level from there.
