I uploaded new demo from 18 Jan 2013. It has same 15 levels that the previous demo. There are only technical changes. I fixed many bugs and polished many details. It has all sounds now. Also I rebuilded graphic output. If you had troubles with fullscreen more - please try this version.
Also I added a few new screenshots.
It's beta now!
Project need beta testers.
If you want be beta tester send me your save file to my e-mail. You can find my e-mail in readme file of the demo. You should complete all (or almost all) levels of the demo because I need testers that can (and want) solve all (or almost all) levels of the full version (I already have "testers" that drop game before 6-th level). I promise mention in credits for any good beta-tester and free access to following versions of this game. Main condition - you must not distribute full version before official release.
Expected date of release is the end of february or the begin of march 2013.
More exact date of release will be later.
