Magic Jewelry is an endless puzzle game, so I didn't technically "finish" it per se. I however, did "complete" the game by scoring over 10,000,000 points and making the score counter loop back to zero as a result. After nearly 25 years since this game was made, what happens when over 9,999,999 pts gets scored is finally discovered for all to see. Apparently, Hwang Shinwei never thought anyone would even get this far into the game, so he didn't bother programming a cap for any of the game's values.
Not shown in this video: apparently, when level 256 is reached, the falling jewels revert back to a manageable level 000 speed. Least those Taiwanese programmers learned from the whole Pac-Man crashing level, at least....
Maybe I will try to attempt a "100,000 jewel" completion or a "level 1,000" completion.... heck, I might try to attempt the same run in Magic Jewelry 2...
