-Survival Mode

the first thing I added was a survival mode into custom mode were Sammy would be replaced by the one in level 4 and you would see how long you can survive

-Having to get TNT

for this the idea was that you would have to look around the map for TNT before you would be able to kill Sammy Slaphead which would make the game a bit longer since it is very short and make it a bit harder

-Locked Doors

this would of added onto the last idea were you would have to find a key before unlocking the door to get the TNT in whatever room it was in

-The Ability to look behind you

this would just make you able to look behind you, thats all but if I did add this there would of been a character that would appear behind you making you unable to look behind you or go back to the previous room

-Scrapped Character in pictures

there was a character called Robert Slimy Arms that would appear in the pictures in rooms and play a glitch sound effect and you would have to leave the room before you die, I added him into Sammy Slapheads House (Level 1) and added him into Bunsen Burgers (Level 2) although in a broken state before eventually replacing him with Chris Tall Balls who is a character that plays into the story while Robert Slimy Arms wouldn't

That is all I want to talk about at the moment but there are more ideas I had that I didn't talk about here
