There is no port specifically for android, but the web version of the game may run in JOIPlay. It isn't specifically tested for it though, so your mileage may vary.
If you've done the futanari scene with Daisy, you won't be able to return there because there are no more scenes with her after that. Otherwise it might be a bug.
I am planning to rework how femininity and depravity give the player more power somewhat, but as of right now losing shouldn’t actually be making the player stronger, generally the stat changes that result should make them slightly weaker. Usually though, losing to an enemy will give you femininity, which makes you stronger, and depravity, which makes you weaker. As long as the depravity gained is twice as much as the femininity gained, or more, the player won't be getting stronger.
As for the other point, it is hard to balance out the “lose to see content” mechanic, but I don’t really see a different way to go about it. The player gains power from feminizing themselves to incentivize the player to do so, because that is what the game is about. What would be the alternative, feminization making them weaker? Because that wouldn’t really make any sense. The best answer I could come up with for the “lose to see content” thing was the linking devices, allowing you to continue onwards several times after losing. They let the player choose between trying to avoid losing as much as possible by using the charges to heal between fights, or just fighting until they lose and having the linking charge heal them automatically. With the rework I am planning, I’m hoping to balance the game better as well, so that even if you have feminized yourself a lot, the enemies aren’t trivially easy.
