Congratulations on your game, it's a nice submission. I like it and fit well the theme. The game looks nice! The backgrounds and music are very impressive, especially done in 3 hours!
Regarding the gameplay, I would maybe apply potions by clicking on them directly, I was confused on my first run. I would also put them in the same order as the warrior stats.
You can also increase your stats very high, have you thought about adding a limit to your stats?
