Sorry for the rapid update, however, I thought this script was important enough to find and write a script for, so here it goes:
Update 1.2:
created and added Custom Seed w/ Achievement Script from scratch, based on the request from paulowtt.
Please test and see if it works. from my initial limited testing, everything seemed to work as intended.
I forgot to mention in the last update, I have included an Easy Attach script, not made by me so all credit to the creator of the script, that when activated will automatically attach the cheat engine to the game. Will save you like two clicks.
I tried to find the timers however I am unable/not skilled enough to find those values for some reason. However, all hope is not lost since if you just want to reach the blue womb and/or boss rush, then there is an item named MAMA MEGA! with the id of 483 and use the id in the Player script---> [ Held Items ] ---->Current Item. it's a space use item that once used will open/blow up the boss rush door and blue womb door. its one time use and you should only use it on the floor the door is in order for the doors to open. hope this helps.
regarding the invulnerability script, yeah I didn't create them I just salvaged them. I tested to see if they would just activate and not beyond that and if they did I put them directly in. no problem though just use the player script and set your value for the hearts and then freeze them. that should give you the same result.
As always hope you all enjoy.
