Current state of Replay System

Time for some progress report. Currently, replay system can accurately recreate the game state most of the time. On some occasions, the score can vary, and there are also some very rare cases in which the game state breaks and the replay becomes completely off. I'll look into more ways to try to fix this.

This video example showcases 2 different playbacks of the same replay file. They are almost identical, save for the moment at 0:55 in which the right side doesn't get the extra combo damage, resulting in less score. The left side's score is consistent with the actual gameplay result for reference.

On the other hand, I was also working on replay menu and it's mostly finished. I just need to add prompt for deleting replay and format the text better.
