Well thank you for giving the game another shot :D
The tea is probably going to feel wonky for a while until there's enough content in the game for it to be useful. Most of these teas (so far) are combat related, but the early game enemies are weak, so that's part of why it feels underwhelming. I also wanted to encourage the player to mix the teas together and get crazy combos, so using them independently really isn't the point of the mechanic. I'll probably still update them a bunch until they feel 'right' to me.
Once again thank you for your feedback, your reviews have been very insightful, especially since I'm still struggling with gamedev tunnel-vision and all that :)
