The original was the worse out of the two, constantly getting stuck on walls, Luigi making explosive sounds for some reason, plus having to press delete every level just not to hear a ring sound effect (rings really serve little to no purpose in either game) was just ridiculous. Both games are just avoiding obstacles and not getting hit. Got kinda boring after awhile. The second game had some nice idea's but still suffered from the ring and sticking on walls problem. It was a neat idea with changing size,appearance and motion each every few levels, that idea could be used in a game if done well. Both games are not that good, but there was obvious effort put into it.
