Very fun.
The graphics were amazing i loved the old school games with nw age graphics they were perfect. The sounds were all perect and fit each boss. The controls were alittle hard to mster because it was a pretty hard game. The game itself was very hard but increadibly fun. I really liked the mario one it was pretty tough then the ilnk one just brought you back to the good old days. You should make more of these kinda flash games using all the great classic genres of gaming. Improvements would be to add different difficulties or like training modes so people don't just start off die a few times then get angry and say "too hard it sucks".
