Shadow Depths is very close to it's completion. Currently I am planning to add around 5 more levels, polish existing mechanics and add sounds and music. Hopefully music will be created by my friend soon. Since last update post I've added 4 new levels and tweaked some older levels. Also new mechanics were added. I hope that finall touches will take no longer than 2 weeks and I'll release the game in October.
And as always here are 2 screenshots from latest levels:
