I just finished the game content of the 0.52 ver. I love the art and I hope they add paizuri scenes later. Here are some tips I find that might help someone in the future. Listed in order of appearance:
1>you are supposed to lose against the biker boss with the red glowing eyes, don't waste your consumables with him, just spam end turn until he kills you.
2>when you max a stat it shows "0/number". If you already are maxed out when you meet the kill bill parody trainer, you just need to grind the skill points for training with him. (make her do push-ups is the easiest)
3>sometimes after working as a stripper your battle action points will get cut in half, I found that you can fix it by sleeping. So be aware of your skill points before raiding.
4>when you reach the point to work as a whore, you are supposed to hold the space bar till the "cum" button shows up. (there is no UI in the screen)
I'm not so fond of the grind nature (there should be more ways to earn even more money and more popularity as you level up).
also, If you get stuck, there is an abridged walkthrough in the Patreon link.
