For anyone new to this game, here are some useful tips. Some of these may have been mention earlier in the thread, but I tested them and know they work on version 0.0.8.
1. While you can build barricades out of boxes and barrels, it will not stop an enemy from using their grapple to break though it. This is still useful to do since it prevents enemies from entering a room and sneaking up on you.
2. You can use fruits when being raped. Gold and orange fruits restore stamina and blue fruits reduce, not eliminate, lust. This is very helpful when you are inserted and trying to break free of an estrus enemy and your stamina runs out or lust gets too high.
3. It is tricky and takes some timing, but if you can break line-of-sight and bring your shield up, you have a chance of evading an enemy and having them going back to wandering. I have done this by going into the corridors and bringing the shield up or running around the room that has a wall in the middle and getting lucky.
I have been enjoying this game even though it is far from complete. Hopefully we get another update this year that adds a new enemy besides the merchant, though I doubt it.
Also looking forward to seeing the H animations that the merchant will use.
