Ah! So I was being an idiot all along. Thanks a ton, guys.
Since I've only just begun my first game (based on the unfinished Vertical Shooter tutorial on these forums), I may have more questions later on. Stay tuned and watch me flounder, as it were.
EDIT: Speak of the devil.
I just finished up implementing the "enemy ships," but at runtime they come out warped on the game screen, and I haven't the slightest idea why. Since I have no way of showing you what's wrong, I uploaded what exists of the game so far (it's nothing serious, just a test to get used to Construct before I try to handle something larger and/or more ambitious).
