Sorry for the late reply.
I have been on a vacation from the 22nd December. I somehow didn't find the time to post here before I went on that vacation. But anyway I guess it was obvious that I didn't make it in time.

Well, I actually had the core gameplay with 3 enemy types ready. But I was still missing a routine for loading the enemy waves.
Anyway it was still a great experience, as this time I noticed that i have made some progress with solving logical problems in smoother way.
By the way, I am still trying to get the Prototype running and upload it here, despite the Prototype Session. I am trying to finish it in my free time next week.
