I've played for the story (which I've enjoyed) but here are the things that have gone wrong:
1. Save game lost twice: once due to game bug, once due to browser crash.
2. Various glitches have caused me to need to refresh several times, losing the progress of my last battle
3. The 7th battle in the last chapter is SO glitched that I've beaten it twice and am stuck on the battle screen, so I don't even get to know how the game ends.
I understand that you fixed 1, but 2 and 3 also need to be addressed.
