I noticed this long after I had already published and polished the game on Itch.io, so I sadly couldn't fix it. I can easily fix this by simply making so the chick has a bigger hitbox. I am sorry, as I was far too tired at the time to notice ( due to the deadline of the jam ).
I appreciate you for coming back and giving the game another try, and I will do my best to improve the project ( as I was planning to ) as much as I can. I am terribly sorry for any and all inconveniences.
Also, when it comes to the atmosphere, me and my brother worked tirelessly to make the game feel as good as it does. I think adding in a background, visual effects, more sound, and changing the level design ( to be more open ), can give it a better feeling of what we were going for.
Thank you for the honest advice, I too hope you can one day become a master of "Growing Up North"- my first attempt at a large public project with a deadline... ( oddly specific, but that's because I've made a couple large games before- although none of which are as good as GUN )
