No problem! The best part about these jams is getting feedback and learning from what other players are doing. :D Makes me excited for the next one.
In regards to the alchemy and mana, I would consider a different approach from having replenishing mana. (although I think this is viable as well, although carries with it its own pitfalls). I would consider disconnecting the gold nuggets from the health / mana potions entirely (or use them in a much lower ratio and have them drop more often). If possible, I would also lower the barrier to entry of using a potion rather than having to navigate a menu system, maybe binding Health Potions to 1 and Mana Potions to 2 or something. Kinda like how the Diablo franchise makes spamming health and mana potions an integral part of gameplay, it can be done, but it's a pretty big design question for what ends up being most satisfying. Honestly for two weeks of work, your entry already has enough going for it without having to worry about that kind of minutia (but it is fun to consider outside of the time crunch).
