Hei! Vielen Dank for your comment and your suggestions.
The given level can be surely completed with the 3 coming bricks. Every time bricks are generated randomly (more or less) so often times you complete it with less moves.
Couldn't you add a bit details on your issues with color differentiation? The color of bricks doesn't mean a lot. And the "charge" of light-bulbs is differentiated by color, brightnes AND shape so there where no reports on that part yet. But I could miss something, too :)
As for banking part: since you are the first person who actually expressed his wish to purchase the game (and since I do not know much about payment options) I guess I could just give you Lumini Zen as a Welcome Gift :) If that is ok I'll add a (free) Download Key for your account here on itch.io. Please let me know.
