I have a criticism for the game, the fact that losing all your health just results in a game over is kinda not ideal with the corruption system, makes it hard to get to high values of it. personally i think a good way of solving it would be instead or resulting in a game over, it results in a scene or something getting sexed by the xenos, upping all your corruption by like, 5 or something. and then taking like 25% or 50% of your xeno DNA, and then sending you back to start in terms of progression (not storywise though, you'd still have unlocked the features and characters you'd had reached) you'd basically have to start at zone 1 again. at the very least making that an toggleable option would be nice, imo. because for the time being, it is not especially easy to get high corruption values.
I agree, health reaching 0 should not be something that results in a game over. I think a better way of handling health is that it should stop the player from doing runs because their health is too low. In the beginning of the game before the xeno on the ship, the character has to perform tasks that would heal the player, and consequently lower corruption values. But if you interact with the xeno to many times, the med bay used to heal the player will instead heal and corrupt the player as a result of the mixed DNA (or something similar)
