Progress on a little 2D game

For some time now I'm working on a little 2D game. Its actually a sokoban "clone", and yeah, i hear you, there are tons of those around already. But I don't really care, its a game a lot of people still play, even though most of the clones out there don't have fancy graphics and sound effects. I plan to change that with my version ;)
I called my version "Shinju". This should be japanese for "Pearl", can someone from japan please confirm this? ;)
Why "pearl", well look at the screenshots below. If you put the shells on the target tiles, they open up and reveal a pearl. The goal of the game is to collect all the pearls.
Why japanese? Well, the original game originated in japan.

Anyway, here are some screenshots of the progress:

What I still need to do before its finished:
-Create 100-200 levels. Hmmz, boring ;) Maybe i'll look for an existing level pack and ask the author for permission, but I prefer creating my own (so its original)
-finish the level editor (i plan to add a level editor, so people can create their own level packs)
-add some forms for settings, help, etc

If there are any sokoban fans out there who like to beta test, just mail me.

Oh, and now something totally different. I uploaded a skybox to my webstore the other day. Perfect for use in Torque. I have around 30 of these laying around, maybe I'll upload some more (if I find the time).
