Mini-Boss (Part 2.0) 

Mock-up showing route from previous level.

           

This level features the main boss from the end of the level, in this particular mock-up taken from my preliminary sketches,  there features a spikey metal ball which travels along runners, the ball may only from from areas where two lines of runners intersect (creating safe areas). The idea of this is that the ball will fall at random to make an extra layer of difficulty and get in the way of a player who isn't paying attention.

If the player begins the level, i have included a "secret red button" this button will make the ball fall from the next intersection it meets if the button is hit. The ball will damage both players and enemies so using the button can aid the player. This adds to the discussed method of killing each boss in the game within 10 - 15 seconds (To be decided). if the player comes out of the pipe and jumps over to the button asap and hits it the boss will be one-shot and the enemies spawned post-death
