The story mode is still in active development, but there will be one, no concrete time frame but we are aiming for end of summer at the earliest for the full town mode to be done. The paid version also has over 3 times the amount of content as the itch demo, with over 800 items and 5 playable characters, all with unique mechanics and challenge runs.
and as of right now the game is 20% off on steam right now and through the summer sale - we started our sale early to celebrate reaching 3000 reviews on steam. If you want to hold off until the town is implemented I imagine we will be having a sale for our 1.0 launch.
