Ideas:
1) It will make game more challenging with the new unkillable enemy I'm planning to add. So will keep it the same.
2) That achievement is already there. At the time only had 3 achievements programmed. Will change the title to this one because I like this better.
3) Indiana Jones? Will think about it later.
Masturbation:
Regular skin animation just finished a while ago. I will make the rest same as you mentioned but will replace the red one with base animation.
Quality of life:
1) The games inspiration is taken Spelunker nes. I had plans to cart and lift in the game but it wasn't working well. Player always float in air if lift or cart is moved. I manage to do it in other game but not in this one. Thus as the little sister is a genius, came up with teleportation device idea.
2) Maybe she becomes naked after attacked by creatures?
Bugs:
I think first and third have been taken care. Need to fix the second one.
Thanks for the ideas. I hope you are not too disappointed for rejecting some of the ideas.
