Hello! Thank you for your feedback, it's much appreciated!
I'm impressed you didn't found the Memory card #2, actually. I thought it was one of the easiest to obtain, but this is also one of the hiding place I'm the least proud of. Check the living room for a clue.
Attack skills actually does have an utility... later. I admit it can be confusing considering the kind of game it reveals itself to be, if I do update this game after the jam, this is one of the problems I intend to rectify.
Have fun!
