I got back a few times to the game because I kind of liked how brutal it is in current state even if it's all due to bugs in the end. You're super craving for money as a result, praying to encounter Miraculous Cats since it's the only way you won't face a game over.
Phoenix potions don't work, level ups seem to effectively do nothing, or at least your HPs can't be healed above your initial value, and even at level 10 you don't seem stronger.
When bugs are fixed it will be a completely different game and I feel like the game I want to play is actually somewhere in between, maybe consider a hard mode.
Although probably not the intended way I had fun playing the game, congratulations and thanks for sharing, I will surely go back to it after it's fixed too.
