All levels are possible. Instructions are in game. Spam the green flag or there will be 2 yellow things. (One of them is fake and will make level 6 impossible) If you die on the 12th level you can be stuck there forever. (Unless you see inside and press broadcast done)
Credit to @MajesticPie for the platformer base. Credit to a bunch of similar platformers for inspiring me. All sprites except the player/environment was made by me
