Hi, glad you liked it! The demo version here on Itch is actually outdated and I'm going to update the page to reflect that right now.
This is because the game turned out a little too big for Itch. :') The good news is that the free demo on Steam is updated with features that reflect the full release of the game and even has an additional level. It can be found here if you'd like to check it out! https://store.steampowered.com/app/1768920/Splatter/
Thanks again for playing!
