Hello, those enemies will be there in next update.
Hopefully you will find upcoming sets of enemies a little more interesting.
I will make some changes in the code so that you would get game over from sex. No plans for changing the difficulty level yet but will consider it once the update is complete.
I see you love to play difficult game. Why don't you try a contra game I made couple of months ago. I didn't spend much time to polish it so it's a bit buggy but challenge to complete. Here's the link:https://drive.google.com/file/d/1-ipe-Ne8XbC2O7eFP8wtAXnf5_VFsI0X/view
