i know but I can’t find all the switches or make the jumps, I absolutely suck that much. Is there no way to get the gallery otherwise?
Yes, you can use the debug/cheat keys. Press F9 to instantly get all skills. Then make your way back left to the castle area. Additionally, you may also press F10 to be put in front of the Beach Boss, then defeat him and open the chests to get the crimsom scepter. This item unlocks the ability to teleport around, so then just open the teleport screen and TP to the castle.
