Finally finished my game and uploaded it. It`s not much but it works. You can check it here: https://mario138.itch.io/last-survivor
Unfortunatelly it is a little laggy in browser, but I will check it tomorrow after work. At worst I will change it from browser to downloadable.
I will still work on this game even after the Jam ends to learn more things.
Looking at me previous game I can tell this is a huge step forward for me.
Good luck for everyone else :)
