Thaks for the great feedback! My only playtesters were my parents and they don't know much about videogames. When they played it, it looked far to hard, so I made the Enemys spawn less frequently. When a played game myself, it was a bit Boeing and easy for me too. I think next time I am going to make an easy and a hard Mode, so that everybody is happy 😊.
But did you get to the first big Enemy? This is the moment when it gets a bit harder and the real fun starts. If not, I would definetly think it is worth a other try!
