Here's mine: https://tyrannosaurus-games.itch.io/operation-reincarnation Basically you fight the bad guys, get batteries from them and you power The Elevator to explore other precedurally generated levels. Upon death you reincarnate as a different character, with different abilities and so on.
If I remember correctly my best is floor 15 (I didn't have enough batteries to proceed). You can try to beat it, although it might take some time.
I'll try to beat your score!
