The levels are based on Galaga’s Space Invaders spaceships. With a good music (on my taste) and the sound effects of my son 
I found some issues coding this game: for example the sound on the invisible block remains on the hierarchy list with the name of “One shot audio” because the block is not destroyed. This is not an issue, tho but I’ll try to correct it.
I expect to add some information on the GUI with the score and maybe a timer or something like that.
I like it so far and I’m glad to see that I discovered some issues before Ben mention them on the video. This tells me that I’m learning a lot.
Thank you for your comments.
