I'm considering donating to the devs patreon, but before I do, I wanna find out about the state of Roguelove. I've played the demo and I imagine it's out of date to the current state of the game but I wanna check how much. 

In the demo I'm seemingly unable to lose, and the health and lust bars seem to have no effect on me. I take it the game at it's current state has those features? 

Hey there, sorry about the lateness of my reply I must have missed this post.

Compared to the demo the current version is almost like a new game, tons of features have been added and bugs have been fixed. There's more floors to explore and monsters to fight. You can indeed lose now by running out of health or maxing out lust. There's another update coming this month, so definitely consider it!
