Yeah, me and my friend wanted to have three levels and a variation for difficulty. The first level is the one you see in the game. The second was gonna be a bank and the final one would've been a museum with two floors. To add more variation we would've had the number of thieves and their intelligence change. There was also a planned upgrade menu which would've increased the guards sight range, the cameras FOV and a couple other things. However, due to me not knowing anything about UE AI stuff I ended up spending the majority of my time bug fixing the thief AI and so we ended up not having enough time to finish the game. There would also be a mission/contract selection screen similar to the one in Phasmophobia with a difficulty rating and payout display for each mission/contract. The mission/contracts you can choose from would increase in difficulty (and payout) as you successfully completed more missions (so there was a reputation system also planned).
There were also planned cutscenes which would've played out like the comic book scenes from Kick-Ass and Into The Spider-verse. The storyline would've been you are a father and your daughter has cancer. You decided to start a security company to gain some extra cash to help pay for the daughter's medical bills. But, sadly we had to scrap that for time. I plan to add in all of these features when the game jam ends so I can at least say I game is in a somewhat finished state. The game would end when you reached 1 million dollars earned (but you'd be able to continue playing afterwards as well).
