I downloaded the demo and finished, but i had to restart, as in reset save, 2 times.
First time was, when i purified the shrine with the double doors, i headed up to the first moving platform, but i was a bit over eager and fallen down, then i was locked from any progression because the platform didn't come down and the three jump pet didn't help me reach it.
Second time was, when i reached a door button and defeated a girl on it. But as the jump to the door happened, it got stuck because i happened to pick up the girl at the same time, causing a freeze with me not able to do anything and nothing happened. I could go out, but that save needed to be reset.
I don't mind the jump to the door with putting a girl on the platform, but it is kinda unnecessary when the door opens right next to the button.
I see potential in this game, keep it up!
