Hopefully these things are fixed now:
(if not scream at me and I will try to do better next time :p)

• Increased size of weak points on teleporting enemies (now they can actually be hit!)
  
• Ending achievement should now be given to you when you complete the game
  
• Fixed the bug with the missing life sacrifice card in story levels
  
• Changed / reworked Twin Skull boss behavior
  
• Your save game is no longer deleted after beating the game (sorry for including this in the first place qwq)
  
• Added "End Run" button into the ESC menu
  
• Shotgun pickup in intro can not be abandoned

Wow, It's been just a week since the launch and ROSE is already my most downloaded game/thing!! Thank you so much!!!

I know there are still issues with the game (a lot of them), but please be patient, I have a ton of work (working on 3 to 4 games rn), so I might be a little slow when it comes to updating ROSE. I wasn't expecting this game to gain any traction whatsoever, but now that I see that a lot of people are playing it and enjoying it, I know I must make it a better experience for you.
In the past week I (at least) made two tiny hot fixes, that added the option to invert camera movement and fixed (hopefully) an issue with unlocking achievements.

I'm reading all the feedback and compiling it into a list, so I can address the most pressing issues first. I hope you understand that it may take a while though.

And once again, thank you for showing so much interest in this game, I seriously didn't think this is gonna happen OwO
