"Zelda and the Lampshade of No Real Significance" A fun parody of the Zelda games... except I don't know if it's really a parody... But you get to run around as Link doing pointless tasks that pertain to no Zelda story whatsoever. It's pretty funny and quirky.. Plus Zelda!
Alright that's my arsenal of fun flash games... try 'em or not, I at least think they're enjoyable
