From Nekogames (of Cursor*10 fame, blogged about previously on Neatorama), here's a fun little Flash game by Yoshio Ishii, titled Hoshi Saga. The object of the game is simple: find the star. You've got 36 levels.
Link (Can anyone help me with stage 29?) - Thanks Akiro!
Update 3/31/08: Here's Hoshi Saga 2 - Thanks Akiro and CaptainHairy!
1. the girl
2. the gray background with the thick silver stripe
3. the one where the top point of the star is in the upper left and the rest is in the lower right.
Pull her pants down. :)
