Thanks for the feedback! I'll change the description to better explain that it's building bridges and paths. As for the tutorial I'm unsure what you mean, did you try the X button in the top right (I should probably make it stand out anyway)
Losing health is for the idea of rebirth as part of the game, although u can technically beat it without dying, it is intended to retry if u can with a new person.
And finally as for the not being able to press Y I ran into that bug myself but didn't have time to fix it, ( its to do with the icon in the top left that shows if you can place a form or not) however if you jump it should fix!
Overall the game was a lil rushed so I apologise for any bugs and will fix after jam :)
