My nephews were playing BYM and got fed up about the build time. Kids don't wait 14 days for something to upgrade.
They started a base in BP and got very annoyed by glitches and stopped after 1 week.
What's annoying about BP is that they don't provide information about long term plan and the future tech tree. It seems that they go on 2-3 month plan and if it doesn't work, they change the game around.
Personally, I went from 20+ hours of playing time last year down to about 4-5 hrs a week.
What I can see working for Kixeye would be to make a new version of BP 2.0 and rebuild the code under HTML5 instead of flash. It would probably accelerate the game, be less heavy and maybe fix some of the glitches from the start. But then again some of their decisions such as the glowing bubbles, waves and useless moving graphics inside of bases really slow down the display and require a really good video card. The game was using about 400-600 MB of memory to run last year. It is now taking between 600 MB and 1.5 GB of RAM; no wonder people complains about slowness and lag. I'm just happy they haven't added whales, orcas and dolphins in the ocean.
