I have made a prototype of a game and after a while it starts to drop its framerates. Why does this happen? Did I do something wrong?
Here is live prototype.
Develop games in your browser. Powerful, performant & highly capable.
There is nothing we can learn from a live demo. You're best bet would be to post your .capx.
If that is not possible, then you will need to use debug and watch for the number of objects being created, collisions etc.
