So, playing into the game for a bit, I couldn't help but notice a few problems. For starters, I have noticed two items on the bottom right of the bar in the minigame.

Following the last level, I had the first half of the bar filled up and the items colored. But, it'd only give me the second one.

And not the first one, which I've been told is essential to make the game progress as it'd be used to prompt the heart. Without it, while prompting it, it does not further the game but set the states like I clicked on the 'rest' button.

II cannot go further than this as I am essentially locked.

Another thing I have found out is that dying in the minigame makes the monsters that killed you fixed and immobile. You cannot kill them and they do not react to your proximity. That is all, very sorry for bringing this up.

These issues are being addressed and will be ironed out for the public release. Thank you for reporting them!  No need to be sorry, we're grateful you went to such lengths to test it.

Could you clarify what you mean by the last bit, that dying in the minigame makes enemies fixed and immobile?

Thanks again. <3

I am seconding having the issue with the enemies in the minigame sliding to the right when in contact with obstacles, rendering them invincible. The bullets you shoot also are unable to go behind objects even if the player can, they disappear on collision with the sprite rather than the box the player actually collides with
