I managed to complete the Hidden Palace stage, which now includes switch-activated hazards (something that I'm sure will become more common in the future)
To celebrate, I've added some screenshots of the palace to the
SSK Arenas Page, and there will be more uploaded very soon. Also, I've nearly finished the slot gimmick for the improved Casino Paradise arena, so I added a screen that too:
In other news, I just finished fixing a slew of small AI bugs and fixed a couple of other problems that hampered me for quite a while, so now I can get on with finishing what should have been done ages ago (the missing characters).
