Thanks for making a video about the game!!!!
I am sorry to inform you that the demo version of Itch is very old and does not include all the updates and improvements of the full game on Steam. Just to give an example, the initial part after leaving the room has a different level design, the lettering has been improved and the maps contain atmospheric music.
In addition, there have been balances to make the game a little more accessible to those not used to playing action rpg.
I appreciate tips and advices, many have already been implemented, but what you have played is the first part of the game: tutorial and first level, many things will be explained later in the story.
Also, praise you for making it this far without using the 10 attribute points you had available for the 2 levels you acquired.
On Steam you can also find a Walktrought made by a community member.
If you liked it and want to keep playing just out of curiosity, you can buy the game and import your saves so you don't lose your progresses.
Thank you again, have fun!
(ps.: can I ask you if can change the link on your youtube channel and put the link of Steam instead, please? Thank you.)
