Fun game, though didn't realize from the instructions that the recipes need to have the colors in order as i kept messing up the strength potion which was yellow green while the machines to use had the green ones closer to the start, so i kept finishing those first and then putting them in, then wondering why the potion failed. It might have also been nice to have the potions that need 3 ingredients instead of 2 give a few more points, but it works
Plus I also found a little bit of a bug where if the wisp has just been given wood to eat, you can still click on the machines to heat them up while the wisp stays in the furnace.
but it's otherwise a wonderful game and I played it a few times to try and get a nice score, the highest I've managed to get so far is 700, which i guess also means 7 potions I completed
