First demo version.
It worked out the game mechanics, main characters and style.
I assume the following dynamics of the game: 9 levels - 10 is a Boss battle. 5 bosses and about 50 levels of the game. Each cycle is slightly different in its mechanics.
So far, the level with the boss is in development.
I'm also working on a storyline.

There are plans to add non-linearity in the passage of puzzles(while it is implemented poorly)
