Thank! :)
I noticed the movement slowing down too late for me to fix it, as for the audio I'm trying not to rely on pre-made assets. For jams, I personally want the experience of making it all, I feel like becoming a more well rounded dev is my reason for joining jams. I just didn't have time during this jam to make sounds/music I like
Actually, the background is on a parallax layer scrolling at different speeds. There are 4 stacked images, I just forgot to adjust the scroll speeds before I uploaded to make it feel a bit more natural, so they are moving at different speeds, just not in a way that's the most visually pleasing. As for the ship, it was the very last asset I made, and I made it in a hurry and didn't even think about updating the other sprites :D
I'll definitely keep the link to those scripts in mind, and I really appreciate the help :)
