I’m using Construct 3. I was tempted to use the jam as a chance to learn Pico-8 because I’ve never used it, but in the end I decided to stick with what I know! :-D
When it's jam time, it's always best to stay with the devil you know. However, as a Pico-8 maniac, I hope you come over to our side soon. The limitations will set you free.
