Wow, cool guys! I am about to submit my game for this jam. Unfortunately I dont have any spare time this week. I would have liked to add more stuff and polish everything a bit more, but oh well. I learned a lot about gameobjects, instantiating and destroying them, working with public variables in the inspector, made a basic health system and even modeled the - very basic - main character in blender.
So, overall I learned a lot and am happy to keep working on learning this amazing activity :)
(Lets hope, the upload works as I need to do it :D)
