SpreadCheat is the most fun I've had in some time with a game that I completely avoided engaging with in any meaningful way. I solved every one of its simple spreadsheet puzzles by randomly clicking and dragging numbers until something worked, and I had a great time doing it. This is likely because this seems like the intended experience: Office Space your way through with minimal effort, then eat pizza with your bolshy wet wipe of a boss. Have a Steam demo.
SpreadCheat is the Dark Souls of Microsoft Excel simulators, or something
