Two demos of Bloodstained: Ritual of the Night have been released to date in order to demonstrate a portion of the game's development progress. Special versions of the demo subtitled "E3 Ver." were handed on during the Electronic Entertainment Expo festivals of 2016 and 2017.
The E3 2016 demo takes place in Galleon Minerva. In this short demo, the player will guide Miriam through the large ship, culminating in a fight against the boss Vepar on the front mast of the galleon.
A speedrun of this demo can be watched at the official kickstarter page.
The 2017 version of the demo takes place at the Church of Dian Cecht. The player once again controls Miriam fighting through hordes of enemies, with the boss Bloodless waiting at the end of the stage. This demo revealed more enemies, Shards and weapons.
A playable demo which may be based on this one was planned to be delivered to backers in August of 2017, but has since been delayed.
