Hi ! I tried, it's way better I managed to do everything except poison the lake (the cauldron does not reinitialize after it's broken and when it's in this state we can't grab the potion nearby, I think that's why).
Very sweet game. For me it's also very original in comparison to the about 40 other games I've played, both in terms of art (visual & audio) and gameplay :D
The idea for the ending was fun but I think for a jam you did well to rescope ! And I think not actually playing the characters contributes to why your game is so original ?
