thank you so much! Lovely to hear that :)
Regarding the firing laser, yea that's "by design" in the sense, that in this one level the user should hear that something is going on and be prepared. The script is going through the fire circle, but GBS (or GB in general) doesn't let the projectile fly offscreen to onscreen.
So I went with it. In later levels the laser unit only fires when it's on sight.
The other bug was already fixed in the final version, but thank you for bringing it up again :)
