This is a great start!! I think adding music would give it some more vibes and stuff, and let me know if you ever want to talk about coding! I'm new as well but I've been picking up some stuff. I think you could try using the Space Rocks game maker tutorial for example to see how you could make the screen do a wrap around. Games like Vampire Survivors and stuff use such a feature as well, which I'm assuming is what your game is sorta going for!
The spacebar didn't feel like it was doing anything, but I was entertained while I played for a bit :) I hope this is helpful feedback and I think your game is really cool :D

Thank you for the feedback! I do think sound would've really added to it but getting this all done was difficult as is, and time constraints meant I didn't quite get the time to add it. I'll make sure to look into the tutorial you mentioned! Sounds helpful!
The Space key was meant to send out a little guy who was currently following you, but I may have not made it entirely clear in-game. Sorry!
