Thank you for your kind words and feedback as well as taking the time to leave a comment! I appreciate all of them greatly! You bring up a lot of excellent points about the game.
Gang bang animations are being worked on for exactly the reason you cited and the ability to break sex scenes is in the current subscriber build. I am planning a new public release very soon that would include it, a new power up and some updated gameplay animations very soon!
I am always balancing the costs for gallery however at the same time I am still implementing new ways to get coins in game that should help make the process quicker. There will always be more coins in the upcoming levels!
The issues with the boss you mentioned are being worked on, the good news about him though is I am making progress on his sex scene animation and it is the next one to go in game. I want to implement a better signal on the tentacle attacks that alerts the player sooner I just need to spend the time on it, but it is on the list!
Also a tip for that boss he dies if you kill any segment of him with 15 shots. He takes forever if you hit every segment with 14 shots but if you shoot him in the head 15 times he is dealt with pretty quick!
As for exploring levels I like that they are a bit one way and linear. At some point I am adding a stage select so that would serve as a quick way to play a specific level again. I am also still feeling out level design and have more stage elements to build that will enhance stage design!
Thank you for playing the game and leaving feedback! It is always a huge help!
