Thanks for the fair review. I definitly want to finish the project but i had pretty bad headache yesterday so i wasn't able to finish it. Every thing i tried to code yesterday was just garbage as i wasn't able to concentrate so i sadly droped it.
I completely agree with you. I wanted to make a Boss at the end. Also, I wanted to add some animations to the Enemies and Bullets. But there wasn't enough time today to add it all :( .
