I had that! I wanted to write a game like Monkey Island but couldn't work out how to do an inventory system with what was available. I found some blog on the internet where an enterprising soul with the same issue described using prime numbers and a modulo calculation to make an integer act as a bitfield. I wish I could reread that for the nostalgia, seemed like magic at the time.

I moved on to RPG Maker and that was more my speed. I was really into JRPGs at that time.

I accomplished absolutely nothing with either software. I was stuck on imagining the perfect art and perfect story. That inaction remains in me to this day.
