I really liked the changes made to this game to make it more compact. The part at the beginning explaining the world clicked with me well, and i understood the rest of the game in a snap. i actually didnt even ask for more explanation, i just "got it" right away. having Mana as a foil/interactive person to talk to was also nice as well, so that it didnt feel lonely.
i echo kaz-there isnt a way to fail, but the resist part shows promises of somethign cool going to happen. i was actually expecting a button mashing minigame to start up at that moment! still really cool, and the ending hyped me up for even more.
wonderful!! i hope what happens in this project influences more of your own world going forward.
