Thank you! I had such a good time for my first game jam and people like you are the main reason. Appreciate you playing and providing valuable feedback!
I agree the lag does get you by the end and prevents unlimited play. As you correctly pointed out the debris is the culprit as its collision and rigid bodies are left on indefinitely since I liked the look of that. But in the end there needs to be some relief. I was thinking about a little cleaning bot that would sweep the floors for comedic effect and maybe even push them all under the rug or into a rat hole in the back or something.
Recycling the debris possibly with a pooling strategy so that only a fixed number are on the ground at any one time makes sense as well. Thanks!
