I'm glad you enjoyed the dialogue! He's a sassy one :P
Solid feedback on the platforming. It's intended to be a little challenging, but I think the ability to double and triple jump mitigates that. The slimes, uhh, let's say are good at hiding... Definitely will fix that.
Let's also just say the wizard gets kinda tired after the first attack and needs to take a breather ;) (it's not a bug, it's totally a feature)
