Slowly but steadily, Wasabi Defense is crawling through the development process. Here’s the latest screenshot of my work:

The enemy pictured here is the second gunship. This ship actively tracks the player and fires bursts of plasma bolts. They always operate it pairs. One ship is hunting the player while the other one evades him. It works pretty well!
As you probably see, I also changed the background a bit. The density of the stars is a bit different and, most important of all, I added a nebula. I had no idea how to get started on this, but eventually it turned out quite easy and the result is, even though I say it myself, quite spectacular. Expext a tutorial on this very soon!
