Back when I was 13 or so, I wrote a sokoban inspired puzzlegame called Complex. I even wrote two sequels and it got some attention on BBS-es (for those not in the know, that was pre-internet when we still had the wooden guilder).

In 2004 I redesigned the game, wrote 60 new levels and polished up a new version with my brother in law. We released in for Pocket PC and it was received quite well. It was a 2-time runner up for Handango’s People’s Choice Award and was nominated for “Best Puzzlegame of the Year” by Pocket PC Magazine.

Here’s one of the many positive reviews:
