I got it, beat the game.
good game, once you know what to do.
but it would be nice if there was some better control scheme, I mean sometimes you have to flip between refresh and stop repeatedly.
so having to use A up arrow A in between, before you can use the next spell is kind of annoying :-/
it's a good game, it just needs to many button presses to switch between spells.
but PLEASE, dont make it mouse wheel based.
cause the mouse wheel is the most inaccurate thing ever.
one idea would be to assign the spells to number keys and have some pause button somewhere.
or q and e to scroll to the next or prev spell.
or something like that :-)
