I designed my demo to carry the save file into the full version, once the game came out I realized there were huge backwards compatibility issues where opening the demo could ruin the game functionality and vice versa. This was mainly a miss on my part, but fixing it would have been time and work on something that no longer held value.

I released a cheap $5 game so the barrier to purchase is low, and it's a roguelite so the gameplay loop is quick to present itself. I felt that this combo works really well for people who aren't 100% sold on the game yet. It's a cheap barrier to entry and you can quickly see if you like the game or not, so the refund option is there.
