Good Job
Its a good "Beta" version of the game, I enjoyed it, but on the other hand, I did beat it in one try.
So, when your making your REAL one, make it with more levels.
More difficulty (Make it so there are MANY tubes to go, and most of them are wrong, but the player has to find out which is correct, EX. Mario Party, with the Treasure going in the pipes, who knows where it will go.
Have some music in it, motivate people to play the game more.
Have some more Evil looking lava, and say also, during the levels, the lava can like, Spit a chunk of volcanic blob of lava at you, and you have to dodge it, that will SURELY increase the difficulty.
