Thanks! Yeah, control hints are surely something that will need improvement (time and rewriting lvl1 mechanics haha), though it's not so easy to do this in more subtle, way (something other than "PRESS X TO Y" kinda thing). 

BTW in case you haven't guessed it by now, you need to press SPACE/ENTER to use the key. Second level is a bit better hinted, though you will not be held by hand through all of it :)

Thanks for nice words!
