Help with changing space invaders clone

Hi i’m trying to edit this space invaders clone so that the aliens move to the left rather than moving down. I also am having trouble with the player sprite as it keeps dissapearing off screen, can anyone help with this? (4.2 MB)

It is not really my business but seeing that you are a student and working on school projects (Desperately need help with Defold project) I really hope you’re not planning to hand in a slightly modified version of someone else’s work (My game made with defold - a Space Invaders clone)?

Also, it is a really big ask to get someone to download a full project and analyse it and suggest a solution for you. What have you attempted on your own? Have you identified which script is responsible for moving the aliens? Maybe share it here (as text) and then also share what you have tried so far.
