Outside knowledge is going to be missed by a lot of players, haha. I am really glad that this is of help to you, knowing what I am still doing here on the itch.io website is important and means at least something for you devs, really makes me happy.
I love puzzle games, and your game has some where you have to beat the bosses in a certain way. I could figure that out, except the very last one that combin all of the other three powers, plus his powers.
Most importantly, thank you for this lovely game, and huge thanks for the follow... Really means a lot to me, probably as the same feeling you had when you saw my respond on your post XD
