#Coin Dive (Some empty blocks. The user climbs them and runs off; coins line their path as they fall back to the ground.)
#Free power-up. (Sets the player up to get a power-up with little or no challenge.)
#Straight. (A straight stretch of land with maybe one enemy and maybe some coins or blocks.)
#Single Pit (A pit that the user must jump over; rocks on either side.)
#Bowling Alley (A red koopa right before a long line of enemies. Kill them all in a row by throwing the shell.)
#Cannon Line (A stack of 2-3 canons.)
#Maze (A... y’know... maze.)
#Lemming Trap (A little pit with a few enemies that jump down into it.)
#Platform Jump (A bunch of platforms to jump between.)
#Pipe Jump (A bunch of thin pipes to jump between. This can be rendered much easier, because sometimes the space between the pipes is filled.)
