Love the game!! Some things I found myself wanting/needing:
A tutorial. It took me a while to understand what I was looking at.
The wave timer definitely adds a sense of urgency but I wished I had the option to start the new wave whenever I was ready. I needed more time to understand what I was looking at and all the stats or maybe I wanted to explore a bit before going on to another wave or visit the shop and buy/sell. I know the game has break periods every few waves but idk I would have liked the waves to not be forced. Maybe a toggleable wave timer? Or just pause the wave timer when you're in the character screen so you can take the time to look at gear and stats.
I would also love to see cumflation on the character with how much cum you end up taking in your ass and mouth and I loved that the mimic locked a butt plug in you to keep it all inside for a while.
