Glad you enjoyed it and thanks for the kind word, thank you!
The stop on expanding is a mechanism if you are too close to the edge so you don't get stuck in the wall, but if it happens in the middle of space that's a bug😅.
I got that the first time I installed it but then it worked the second time. I was in a bit of a hurry uploading and I didn't find what was wrong when I check the code, and it never came up in game maker when running it. I'm going to do some polish and fixing after the jam so thanks for posting the exact error code!
