Hey! No, I actually used bitsy, which is a very small and restrictive engine. Basically all it can make are narrative "games" like this, that move from room to room telling a story through text. On the other hand it makes it really easy to make games like this! It's the first time I used bitsy (and my first purely narrative game), and I considered using a multi-purpose engine, but have wanted to try bitsy for a while. I'll definitely check out your game too!
I have never heard of PICO-8, based on your description it somewhat with making puzzle games. I like to use RPG Maker because I like RPGs since they are more story focused which are the kind of games I like. Although with my Game Jam entry I wanted to see if I could make something that wasn't an RPG.
Well, you can make anything in PICO-8, not just puzzle games. It's not really better for any one genre. But it has lots of restrictions that make it better for smaller games, like a 128x128 resolution, 16 colors, restricted memory, etc. Basically you can make small, old school pixel art games with it, like NES or Commodore 64 and similar stuff.
