As you read, this Pre Release focuses exclusively on optimization. It was a major issue especially in later nights, because the game could crash very frequently.

Steps that have been taken were to compress the colors of the game, reduce animation frames, make big objects smaller and rescale them in game and more.

If you're still experiencing crashes from pre release 3, be sure to report. Details as to when the crash occured and how long you've had the game open for would be appreciated.

Still looking for bugs, if any. The tic tac toe hasn't been fixed yet, but I do know about it.

Same deal as always, you gotta redownload the game to get pre release 3.
