Had fun with this game, but I do find the point scaling to go through the roof if you mostly get point bonus eggs. I was able to out pace the game's difficulty and get 150 lives. It is truly "Forever".
I do find the "late game" mazes to feel way too big and time consuming, a part of me wishes there was a generation option to cap the size and get difficulty from something else.
I ended up stopping at R100 and had a great time.
